Reduce the following rational number in its lowest form: -60/72

Solution:

Given, the rational number is -60/72

We have to reduce -60/72 to its lowest form

We know that, to reduce the rational number to its standard form, we divide its numerator and denominator by their HCF

60 = 2 × 2 × 3 × 5

72 = 2 × 2 × 2 × 3 × 3

HCF of 60 and 72 = 2 × 2 × 3 = 12

Now, -60/12 = -5

72/12 = 6

Therefore, -60/72 = -5/6
