Question

5/9-3/8 estimate the difference

Answer 1

The answer to the problem is 13/72 

Answer 2

we are given

`(5)/(9)-(3)/(8)`

step-1: Firstly , we will find common denominator

we can see that denominators are 9 and 8

so, we will find LCM of 9 and 8

LCM(9,8)=72

step-2: now, we will make each denominators =72

so, in order to make denominator =72 , we will multiply by 8 in top and bottom of first term

and we multiply by 9 in top and bottom of second term

we get

`(5*8)/(9*8)-(3*9)/(8*9)`

`(40)/(72)-(27)/(72)`

step-3: We can see that both denominators are same

so, we can combine numerators by having common denominators

`=(40-27)/(72)`

`=(13)/(72)`

so, we get

`(5)/(9)-(3)/(8)=(13)/(72)`..............Answer
