If a : b = 5 : 8, x : y = 25 : 16; evaluate ax a x : by

Question 1 Report

If a : b = 5 : 8, x : y = 25 : 16; evaluate $\frac{a}{x}$ : $\frac{b}{y}$

125 : 128

3 : 5

3 : 4

2 : 5

Answer Details

a : b = 5 : 8 = 2.5 : 40
x : y = 25 : 16
$\frac{a}{x}$ : $\frac{b}{y}$ = $\frac{25}{25}$ : $\frac{40}{16}$
= 1 : $\frac{40}{16}$
= 16 : 40
= 2 : 5
