Answer:
100 and 80
Step-by-step explanation:
let the numbers be n and [tex]\frac{4}{5}[/tex] n , then their sum is
n + [tex]\frac{4}{5}[/tex] n = 180 ( multiply through by 5 to clear the fraction )
5n + 4n = 900 , that is
9n = 900 ( divide both sides by 9 )
n = 100
and [tex]\frac{4}{5}[/tex] × 100 = 4 × 20 = 80
the numbers are 100 and 80
