Addition using standard units (litre and ml)

Addition using standard units (litre and ml)

To add litre and ml, first convert the litre into ml.

EXAMPLE 1

Add: 1 l + 345 ml

1 l + 345 ml = (1 x 1000 ml) + 345 ml

= 1000 ml + 345 ml

 =1345 ml

Note: 1000ml = 1 litre

EXAMPLE 2

Add: 7 l + 9 ml

7 l + 9 ml = (7 x 1000 ml) + 9 ml

= 7000 ml + 9 ml

= 7009 ml.

EXAMPLE 3

Add: 63 l 380 ml and 14 l 175 ml

Step 1:

Start from millilitres.

380 ml + 175 ml = 555 ml

Step 2:

Then add litres. 63 l + 14 l = 77l
