Addition of length

Addition

Example

1. Find the sum of the following.

(i) 7 m 25 cm + 15 m 50 cm

Example calculation of meters and centimeters

Sum = 22 m 75 cm

Step 1: Start from centimeter

\( 25 \text{ cm} + 50 \text{ cm} = 75 \text{ cm} \)

Step 2: Add meters

\( 7 \text{ m} + 15 \text{ m} = 25 \text{ m} \)


(ii) 5 km 700 m + 12 km 450m

Example calculation of kilometers and meters

Sum = 18 km 150 m

Step 1: Add meters

\( 700 + 450 = 1150 \)

Step 2: Convert meter into kilometer

\( 1150 \div 1000 = 1 \text{ km } 150 \text{ m} \)

Step 3: Add 1 km to the km column

\( 1 \text{ km} + 5 \text{ km} + 12 \text{ km} = 18 \text{ km} \)

\( 1 + 5 + 12 = 18 \)

Example
