Weight of the apples = 18 kg 387 g = 18.387 kg

Weight of the oranges = 14 kg 270 g = 14.270 kg

Total weight of apples and oranges = 18.387 kg + 14.270 kg = 32.657 kg

Total weight of all the three fruits = 36 kg 357 g = 36.357 kg

Weight of mangoes = 36.357 kg 32.657 kg = 3.700 kg = 3 kg 700 g

Thus, the weight of the mangoes is 3.7 kg or 3 kg 700 g.

SUMS INVOLVING MULTIPLICATION AND DIVISION

Example 12: Multiply 35 kg 634 g with 15.

First, convert 35 kg 634 g to kg.

35 kg 634 g = 35.634 kg

Now, multiply 35.634 kg with 15.

So, 35.634 kg × 15 = 534.510 kg = 534 kg 510 g

Example 13: Divide 55 km 608 m by 6.

First, convert 55 km 608 m to km.

55 km 608 m = 55.608 km

Now, divide 55.608 km by 6.

So, 55.608 km ÷ 6 = 9.268 km

Multiply. Write the answers in your notebook.

a. 589 m 33 cm with 11 b. 143 850 m with 7

c. 261 g 87 mg with 9 d. 345 km 56 m with 15
