Quick Tip
While adding mL if the total is 1000 mL or more than 1000 mL, take 1 to
litre’s column as 1000 mL = 1 L. For example, add 2 L 400 mL and 1 L 750 mL.
L mL
Step 1: Add the millilitres.
2 400
400 + 750 = 1150
+ 1 750 Since 1000 mL = 1 L
1150 Carry over 1 to L column.
L mL
1 Step 2: Add the litres.
2 400
1 + 2 + 1 = 4
+ 1 750 So, 2 L 400 mL + 1 L 750 mL
4 150 = 4 L 150 mL
11 Solve these.
