To convert a fraction into decimal, we need numbers like 10, 100, 1000 in the denominator

So here the number is 20 so we can multiply it by 5 to get 100

And the number in the numerator can be any number We don't need to make it 10, 100 or 1000 ......

So if we will multiply 20 by 5 we need to do the same in the numerator

47× 5= 235

20×5= 100

235/100

=2.35 is the answer
