Answer:

The numbers are -15 and 100

[tex]\frac{2}{10} +\frac{-15}{100} =\frac{5}{100}[/tex]

Step-by-step explanation:

we have

[tex]\frac{2}{10} +\frac{x}{100} =\frac{5}{y}[/tex]

Solve the left side

[tex]\frac{2}{10} +\frac{x}{100} =\frac{20+x}{100}[/tex]

so

[tex]\frac{20+x}{100}=\frac{5}{y}[/tex]

equate the numerators and the denominators

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

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

therefore

The numbers are -15 and 100

[tex]\frac{2}{10} +\frac{-15}{100} =\frac{5}{100}[/tex]
