Find answers to the following. Write and indicate how you solved them.
(a) Is 5/9 equal to 4/5?
(b) Is 9/16 equal to 5/9?
(c) Is 4/5 equal to 16/20?
(d) Is 1/15 equal to 4/30?
Solution:
We use the concepts of fractions, reduce fractions, and comparing fractions to answer the given question.
(a) 5/9 and 4/5
Cross-multiply the denominators, we get
5 × 5 = 25 and 4 × 9 = 36
Since 25 ≠ 36
Therefore 5/9 is not equal to 4/5
(b) 9/16 and 5/9
Cross-multiply the denominators, we get
9 × 9 = 81 and 16 × 5 =80
Since 81 ≠ 80
Therefore, 9/16 is not equal to 5/9
(c) 4/5 and 16/20
Cross-multiply the denominators, we get
4 × 20 = 80 and 5 × 16 = 80
Since 80 = 80
Therefore, 4/5 equal to 16/20
(d) 1/15 and 4/30
Cross-multiply the denominators, we get
1 × 30 = 30 and 4 × 15 = 60
Since 30 ≠ 60
Therefore, 1/15 is not equal to 4/30
