__Exercise
2.1__

** **

**1. Fill in the blanks**

(i) 250 *ml* + ½ *l* = __¾__*l*

250 ml = ¼ *l* + ½ *l* = ¾ *l*

(ii) 150 *kg* 200 *g* + 55 *kg* 750 *g* = __205__ *kg* __950__*g*

(iii) 20 *l* – 1 *l* 500 *ml* = __18__ *l* __500__*ml*

(iv) 450 *ml* × 5 = __2__*l* __250__*ml*

450 *ml* × 5

2250 *ml* ÷ 1000 = 2*l*
250 *l*

(v) 50 *kg* ÷ 100 *g* = __500__g

50 *kg* (50000/100) = 500 *g*

** **

**2. True or False**

(i) Pugazhenthi ate
100 *g* of nuts which is equal to 0.1 *kg.*** [True]**

(ii) Meena bought 250
*ml* of buttermilk which is equal to 2.5 *l.***[False]**

**(250 ml ÷ 1000 =
0.250l)**

(iii) Karkuzhali’s bag
1 *kg* 250 *g* and Poongkodi’s bag 2 *kg* 750 *g*. The total weight of their bags 4 *kg*.** [True]**

(iv) Vanmathi bought
4 books each weighing 500 *g*. Total weight of 4 books is 2 *kg*.**[**True**]**

(v) Gayathri bought 1 *kg* of birthday cake. She shared 450 *g* with her friends. The
weight of cake remaining is 650 *g*.**[False]**

**[1 kg 000g ] – [0kg 450 g] = 0kg 550g**

**3.
Convert into indicated units:**

**(i)
10 ***l*** and 50 ***ml*** into ***ml*

**(ii)
4 ***km*** and 300 ***m*** into ***m*

**(iii)
300 ***mg*** into ***g*

**(i) 10 l and 50 ml into ml**

10*l* 50 *ml* = (10 × 1000) *ml* + 50 *ml*. __(1
l = 1000 ml) __

= 10000 *ml* +50 *ml *

= 10050 *ml*

**(ii) 4 km and 300 m into m**

4 *km* 300 *m* = (4 × 300) *m* + 300 *m* __(1
km = 1000 m)__

= 4000 *m* + 300 *m*

= 4300 *m*

**(iii) 300 mg into g**

300 *mg* = 300 ÷ 1000 *g* __(1000 mg = 1 g)__

= 0.3 *g*

** **

**4.
Convert into higher units : **

**(i)
13000 ***mm*** (***km,
m, cm***)**

**(ii)
8257 ***ml*** (***kl,
l***)**

**(i) 13000 mm (km, m, cm)**

13000 *mm* = (13000 ÷ 10) *cm* = 1300 *cm* __(10 mm
= 1 cm)__

13000 *mm* = (13000 ÷ 1000) m = 13 *m* __(1000 mm
= l m)__

13000 *mm* = (13000 ÷ 1000000) *km*

= 0.013 *km* __(1000000 mm = 1 km)__

**(ii) 8257 ml (kl, l)**

8257 *ml *= (8257 ÷ 1000) *l* = 8.257 *l* __(1000
ml = 1 l )__

8257 *ml* = (8257 ÷ 1000000) *l* = 0.008257 *kl* __(1000000
ml = 1 kl)__

** **

**5.
Convert into lower units :**

**(i)
15 ***km*** (***m, cm, mm***) **

**(ii)
12 ***kg*** (***g, mg***)**

**(i) 15 km (m, cm, mm)**

15 *km* = (15 × 1000000) *mm* = 15000000 *mm*

__(1000000 mm = 1 km)__

15 *km* = (15 × 100000) *cm* = 1500000 *cm* __(100000
cm = 1 km) __

15 *km* = (15 × 1000) *m* = 15000 *m* __(1000 m
= 1 km)__

**(ii) 12 kg (g, mg)**

12 *kg* = (12 × 1000000) *mg* = 12000000 *mg*

__(1000000 mg = 1 kg)__

12 *kg* = (12 × 1000) *g *= 12000 *g* __(1000 g
= 1 kg)__

** **

**6.
Compare and put >or< or = in the following:**

**(i)
800 ***g*** + 150 ***g*** ******** 1 ***kg*

**(ii)
600 ***ml***+400 ***ml*** ******** 1 ***l*

**(iii)
6 ***m*** 25 ***cm*** ******** 600 ***cm***+25 ***cm*

**(iv)
88 ***cm*** ******** 8 ***m*** 8 ***cm*

**(v)
55 ***g*** ******** 550 ***mg*

(i) 800 *g* + 150 *g* [<] 1 *kg*

(ii) 600 *ml* + 400 *ml* [=] 1 l

(iii) 6 *m* 25 *cm* [=] 600 *cm* + 25 *cm*

(iv) 88 cm [<] 8 *m* 8 *cm*

(v) 55 *g* [>] 550 *mg*

**7. Geetha brought 2 ***l*** and 250 ***ml*** of water in a
bottle. Her friend drank 300 ***ml*** from it. How much
of water is remaining in the bottle**?

Water in a bottle = 2*l* 250 *ml*

Her friend drank water =
0*l* 300 *ml*

**Remaining water in the bottle = 1 l 950 ml**

** **

**8.
Thenmozhi’s height is 1.25 ***m*** now. She grows 5 ***cm*** every year. what would be her height after 6 years**?

Thenmozhi’s height now = 1.25 *m* = 125 *cm*

Height she grows in one year = 5 *cm*

Height she grows in 6 years = 6 × 5 = 30 *cm*

After 6 years her height = Now her height + 30 *cm*

= (125 + 30) *cm*

= 155 *cm*

**After 6 years her height = 155 cm.**

** **

**9.
Priya bought 22 ½ ***kg ***of onion, Krishna
bought 18*** 3/4 kg ***of onion and Sethu
bought 9 ***Kg ***250 ***g*** of onion.what
is the total weight of onion did they buy**?

Weight ofonion Priya bought = 22 ½ *kg*
= 22 *kg* 500 *g*

Weight ofonion Krishna bought = 18 ¾ *kg*
= 18 *kg* 750*g*

Weight of onion Sethu bought = 9 *kg* 250*g* = 9 *kg*
250 *g*

**Total weight of onion they bought = 50 kg 500g**

** **

**10. Maran walks 1.5 ***km*** every day to reach
the school while Mahizhan walks 1400 ***m***. Who walks more distance and by how much**?

Distance walks by Maran = 1.5 kg = 1500 *m*

Distance walks by Mahizhan = 1400 *m* = 1400 *m*

**Maran walks more distance = 100 m**

** **

**11. In a JRC one day camp, 150 ***gm*** of rice and 15
***ml*** oil are needed for a student. If there are 40 students
to attend the camp how much of rice and oil are needed**?

Rice needed for a student = 150*g*

Rice needed for 40 students = 150 × 40*g* = 6000 *g* =
6 *kg*

Oil needed for a students = 15 *ml*

Oil needed for 40 students = 15 × 40 *ml* =
600 *ml* = 0.6 *l*

**Rice needed for 40 students = 6 kg**

**Oil needed for 40 students = 0.6 l**

** **

**12. In a school,** **200 litres of lemon
juice is prepared. If 250 ***ml*** lemon juice is
given to each student, how many students get the **j**uice**?

Amount of lemon juice prepared = 200*1*

= 200000 *ml*

Amount of juice given to one student = 250 *ml*

Number of students get the juice = 200000 ÷ 250

= 800

**Number of students get the juice =
800**

** **

**13.
How many glasses of the given capacity will fill a 2 litre **j**ug?**

**(i)
100 ***ml***_____**

Capacity of jug = 2*1* = 2000 *ml*.

Capacity of a glass = 100 *ml.*

Number of glasses needed = Capacity of a jug / Capacity
of a glass

= 2000 / 100

= 20

**20 glasses of capacity 100 ml,
will fill a 2 litre jug. **

**(ii)
50 ***ml***_____**

Capacity of a glass = 50* ml*.

Number of glasses needed= Capacity of a jug / Capacity
of a glass

= 2000 / 50 = 40

**40 glasses of capacity 50 ml, will fill a 2 litre jug.**

**(iii)
500 ***ml***____**

Capacity of a glass = 500 ml.

Number of glasses needed = Capacity of a jug / Capacity of a
glass

= 2000 / 500 = 4

**4 glasses of capacity 500 ml, will fill a 2 litre jug.**

**(iv)
1 ***l***_____**

Capacity of a jug = 1 *l*.

Number of glasses needed = Capacity of a glass / Capacity of a
glass

= 2 / 1 = 2

**2 glasses of capacity 1 l, will fill a 2 litre jug.**

**(v)
250 ***ml ***_____**

Capacity of a jug = 250 *ml*.

Number of glasses needed = Capacity of a glass / Capacity of a
glass

= 2000 / 250 = 8

**8 glasses of capacity 500 ml, will fill a 2 litre jug.**
