C. Arrange the following measures in ascending order.

1. 0.25 kg, 5 hg, 126 g, 70 dag

2. 0.3 daL, 57 dL, 2 L, 86 mL

3. 185 mm, 0.023 dam, 72 cm, 0.02 hm

4. 31 mm, 1 hm, 87 dm, 0.3 km

Addition and Subtraction of Metric Measures

We add or subtract the metric measures by arranging them according to

place-value chart or expressing them into a single unit.

Example 4: Add: 3 km 5 hm 7 dam 9 m 8 dm, 5 km 5 dam 8 m 2 dm and

3 hm 4 dam 4 m 5 dm.

Solution: Add ordinarily by arranging the measures in place value
chart.

km hm dam m dm
Write 0 in the place where no
3 5 7 9 8 measures are given.
+ 5 0 5 8 2
As 5 km 5 dam 8 m 2 dm = 5 km
+ 3 4 4 5
0 hm 5 dam 8 m 2 dm.
8 9 8 2 5

Converting the measures into metres, we have
→
3 km 5 hm 7 dam 9 m 8 dm 3 5 7 9 . 8 m
→
5 km 5 dam 8 m 2 dm + 5 0 5 8 . 2 m

→
3 hm 4 dam 4 m 5 dm + 3 4 4 . 5 m

8 9 8 2 . 5 m

Ans. 8 km 9 hm 8 dam 2 m 5 dm or 8982.5 m.
