Let us learn how to subtract different units of mass. Here, kg and g are arranged in different columns and then subtracted like ordinary numbers.
1. Subtract 138 kg 165 g from 362 kg 241 g.
Solution: Let us subtract. Step I: Arrange the numbers vertically. Step II: Write the weights to be subtracted in kg and g as shown here. Step III: First, subtract grams from right and then subtract kilograms. |
Thus, 362 kg 241 g – 138 kg 165 g = 224 kg 76 g
Word Problems on Subtraction of Weights
1. A box contains 4 bags of sugar. The total weight of all 4 bags is 6 kg 380 grams. What is the weight of the box in grams?
Solution:
Weight of the box = 6 kg 380 g
6 kg 380 g = 6 × 1000 g + 380 g
= 6000 g + 380 g
= 6380 g
So, weight of the box in grams is 6380 g.
2. Sophia bought 26 kg 380 g of wheat. She used 5 kg 433 g to make wheat flour. How much wheat is left with her?
