Question

Fill in the numbers to find a Sum

Answer 1

The numbers are -15 and 100

`(2)/(10) +(-15)/(100) =(5)/(100)`

Explanation:

we have

`(2)/(10) +(x)/(100) =(5)/(y)`

Solve the left side

`(2)/(10) +(x)/(100) =(20+x)/(100)`

so

`(20+x)/(100)=(5)/(y)`

equate the numerators and the denominators

20+x=5 ------> x=5-20=-15

100=y -------> y=5

therefore

The numbers are -15 and 100

`(2)/(10) +(-15)/(100) =(5)/(100)`
