Addition using standard units (litre and ml)

4th Maths : Term 3 Unit 3 : Measurements

To add litre and ml, first convert the litre into ml.
EXAMPLE 1

Add: \(1\,l + 345\,ml\)

\(1\,l + 345\,ml\)
\(= (1 \times 1000\,ml) + 345\,ml\)
\(= 1000\,ml + 345\,ml\)
\(= 1345\,ml\)

Note: 1000 \(ml\) = 1 litre
EXAMPLE 2

Add: \(7\,l + 9\,ml\)

\(7\,l + 9\,ml\)
\(= (7 \times 1000\,ml) + 9\,ml\)
\(= 7000\,ml + 9\,ml\)
\(= 7009\,ml\).

EXAMPLE 3

Add: \(63\,l\; 380\,ml\) and \(14\,l\; 175\,ml\)

Addition of Litre and Millilitre Calculation

Step 1:

Start from millilitres.

\(380\,ml + 175\,ml = 555\,ml\)

Step 2:

Then add litres. \(63\,l + 14\,l = 77\,l\)
