Question 1 of 7

Find the total weight of three items that weigh:
5 3/4 kg, 3 1/5kg, and 7 3/5

Answer 1

16 11/20

Explanation:

5 3/4 = (4 x 5 + 3)/4 = 23/4 kg

3 1/5 = (5 x 3 + 1)/5 = 16/5 kg

7 3/5 = (5 x 7 + 3)/5 = 38/5 kg

23/4 + 16/5 + 38/5

23/4 = (23/4) x (5/5) = 115/20

16/5 = (16/5) x (4/4) = 64/20

38/5 = (38/5) x (4/4) = 152/20

115/20 + 64/20 + 152/20 = 331/20 kg

331/20 = 16 11/20
