We will verify all fraction that will result 4/5

a .

20/25 = 4/5 (Divided numerator and denominater by 5)

b.36/45=4/5 (Divided numerator and denominater by 9)

c.108/135=4/5 (Divided numerator and denominater by 27)

d. 120/165= 25/33

Answer 2

Given fraction = $\frac{4}{5}$

As we have to find the which option is not equivalent to the given fraction,

(a)  $\frac{20}{25}$

Dividing the numerator and the denominator by 5, we get

$=>\frac{20}{25} =\frac{4}{5}$

(b) $\frac{36}{45}$

Dividing the numerator and the denominator by 9, we get

$=>\frac{36}{45} =\frac{4}{5}$

(c) $\frac{108}{135}$

Dividing the numerator and the denominator by 27, we get

$=>\frac{108}{135} =\frac{4}{5}$

(d) $\frac{120}{165}$

For this number there is not any number which we can multiply and divide for getting $\frac{4}{5}$

So, we can say that option (d) is not equivalent fraction of $\frac{4}{5}$.
