Question

20:28=x:7 and 10:y what is the x and y

Answer 1

20/28=x/7
x=7*20/28
x=20/4=5
20/28=10/y
y=10*28/20
y=14

Answer 2

For x,
$\frac{20}{28} = \frac{x}{7 } \\ = > 20 \times 7 = 28x \\ = > x = \frac{20 \times 7}{28} \\ = > x = 5$
For y,

$\frac{20}{28} = \frac{10}{y} \\ = > 20y = 28 \times 10 \\ = > y = \frac{28 \times 10}{20} \\ = > y = 14$
