Question

Circle the fraction which is the odd one out.
(a) 72/24
(b) 57/19
(c) 88/22
(d) 210/70​

Answer 1

The correct option is (c)88/22.

Answer 2

The required "option c) $\dfrac{88}{22}$"  is correct.

Step-by-step explanation:

To check the options:

a) $\dfrac{72}{24}$

The HCF of 24 and 72 = 24

Dividing numerator and denominator by 24, we get

$=\dfrac{3}{1}$

= 3

b) $\dfrac{57}{19}$

The HCF of 57 and 19 = 19

Dividing numerator and denominator by 19, we get

$=\dfrac{3}{1}$

= 3

c) $\dfrac{88}{22}$

The HCF of 88 and 22 = 22

Dividing numerator and denominator by 22, we get

$=\dfrac{4}{1}$

= 4

d) $\dfrac{210}{70}$

The HCF of 210 and 70 = 70

Dividing numerator and denominator by 70, we get

$=\dfrac{3}{1}$

= 3

∴ a) $\dfrac{72}{24}$ = 3, b) $\dfrac{57}{19}$ = 3, c) $\dfrac{88}{22}$ = 4 and $\dfrac{210}{70}$ = 3

Thus, the required "option c) $\dfrac{88}{22}$"  is correct.
