Answer 1

`bb(16/20)`

Explanation:

Given rational number is `4/5`.

a. `5/4` is a reciprocal of `4/5`.

b. `4/5 = (4 xx 5)/(5 xx 5) = 20/25 ≠ 16/25`

∴ `16/25` is not equivalent to `4/5`.

c. `4/5 = (4 xx 4)/(5 xx 4) = 16/20`

∴ `16/20` is equivalent to `4/5`.

d. `4/5 = (4 xx 5)/(5 xx 5) = 20/25 ≠ 15/25`

∴ `15/25` is not equivalent to `4/5`.
