Find 3 ratios that are equivalent to the given ratio. 5:8

timofeeve [1]

$\large\underline{\underline{\maltese{\red{\pmb{\sf{\: Explanation :-}}}}}}$

The given ratio is 5:8, Write it as fraction then multiply the numerator and denominator with same number to get the fractions or ratios equivalent to the given one.

Let's solve!~

$\rule{300pt}{3pt}$

$\large \sf \: 5 : 8 = \frac{5}{8}$

$\sf \: \frac{5}{8} \times \frac{2}{2} = \frac{10}{16} \\ \tt \frac{5}{8} = \frac{10}{16}$

First equivalent ratio is 10:16

$\rule{300pt}{3pt}$

$\sf \frac{5}{8} \times \frac{4}{4} = \frac{20}{32} \\ \tt \: \frac{5}{8} = \frac{20}{32}$

Second equivalent ratio is 20:32

$\rule{300pt}{3pt}$

$\sf \: \frac{5}{8} \times \frac{5}{5} = \frac{25}{40} \\ \tt \: \frac{5}{8} = \frac{25}{40}$

Third equivalent ratio is 25:40.
