Question

Numerator is smaller than the denominator how to solve

Answer 1

see if both the numbers are divisible by a particular number and repeat the process until you get the simplest form

Answer 2

my own way of solving such question is that multiply numerator with the multiples of 10 and denominator also. so why this process you can divide numerator by denominator and get a number which should be divided by that multiple of 10

for example 4/5 = 40/5×10 = 8/10= 0.8
