Chapter 8 – METRIC MEASUREMENTS

Sub-topic 6 : ADDITION AND SUBTRACTION OF METRIC
MEASUREMENTS:

We will learn Addition and Subtraction of Units of Measurement.

There are two steps to be followed:

1. With Conversion

2. Without Conversion(Vertical column method)

We can add the units of measurement like decimal numbers.

Addition of Units of Measurement:

Add 5 m 9 dm and 11 m and 5 dm

Solution:

5 m 9 dm = 5.9 m

11 m 5 dm = 11.5 m

Hence, 5 m 9 dm + 11 m 5 dm

= 17 m 4 dm or 17.4 m

Add 67 km 250 m and 84 km 720 m

Solution:

67 km 250 m = 67.250 km

84 km 720 m = 84.720 km
