Question

1. solve.

a. 2 km 303 m - 556 m
c. express your answer in the smaller unit
338 km 853 m + 62 km 71 m
e. 701 km - 523 km 445 m

Explanation:

Step1: Convert km to m for subtraction in a.

Since 1 km = 1000 m, 2 km 303 m = 2×1000 + 303 = 2303 m. Then 2303 m - 556 m = 1747 m.

Step2: Convert km to m for addition in c.

338 km 853 m = 338×1000+853 = 338853 m and 62 km 71 m = 62×1000 + 71=62071 m. Then 338853 m+62071 m = 400924 m.

Step3: Convert km to m for subtraction in e.

701 km = 701×1000 = 701000 m and 523 km 445 m = 523×1000+445 = 523445 m. Then 701000 m - 523445 m = 177555 m.

Answer:

a. 1747 m
c. 400924 m
e. 177555 m
