Question

The numerator of a fraction is 18 and the denominator is 8. All of the following numbers are equivalent except: a.9/4 b.2 1/4 c. 36/16 d. 6/4

Answer 1

All of the following numbers are equivalent except: b. 2 1/4

Answer 2

The correct answer option is d. 6/4.

Explanation:

If the numerator of a fraction is 18 and the denominator is 8, we can write it as
`(18)/(8)` which is a improper fraction.

`(18)/(8)` can be written as
`2(1)/(4)` in its mixed form.

So we will check which of the options equal
`2(1)/(4)`.

a)
`(9)/(4) = 2(1)/(4)`

b)
`2(1)/(4) = 2(1)/(4)`

c)
`(36)/(16) = 2(1)/(4)`

d)
`(6)/(4)`
`= 1(1)/(2)`

Therefore, d. 6/4 is not equivalent to 18/8.
