Question

Which of the following is not equal to the others?

(A) 6/8 (B) 12/16 (C) 15/25 (D) 18/24

Answer 1

(C) 15/25

All the options given in the question are further simplified as,

(A) 6/8

Divide both numerator and denominator by 2.

= 3/4

(B) 12/16

Divide both numerator and denominator by 4.

= 3/4

(C) 15/25

Divide both numerator and denominator by 5.

= 3/5

(D) 18/24

Divide both numerator and denominator by 6.

= ¾

Comparing all results, (¾ = ¾ = ¾) ≠ 3/5

Therefore, (6/8 = 12/16 = 18/24) ≠ 15/25
