The common factors of 48 and 60 are 1, 2, 3, 4, 6 and 12.

Therefore, HCF (highest common factor) of 48 and 60 is 12.

Now, 48/60 = (48 ÷ 12)/(60 ÷ 12)

[Dividing numerator and denominator by the HCF (highest common factor) of 48 and 60
is 12].

= ⁴/₅.

(iii) ¹²⁶/₉₀

Let us first compute the HCF (highest common factor) of 126 and 90.

Therefore, HCF (highest common factor) of 126 and 90 is 2 × 3 × 3 = 18.

Now, 126/90 = (126 ÷ 18)/(90 ÷ 18)

[Dividing numerator and denominator by the HCF (highest common factor) of 126 and
90 is 18].

= ⁶/₅
