Question

Arrange the ratios $7:20,13:25,17:30$ and $11:15$ in decreasing order.

Answer 1

To arrange the ratios, we need to find their fractional values

$7:20=\frac{7}{20}=0.35$

$13:25=\frac{13}{25}=0.52$

$17:30=\frac{17}{30}=0.57$

$11:15=\frac{11}{15}=0.73$

Arranging these numbers in decreasing order we get

$0.73,0.57,0.52,0.35$

$11:15,17:30,13:25,7:20$
