Question

Convert into percentages and arrange in descending order.

$\frac{4}{5},\frac{3}{10},\frac{17}{20},\frac{18}{25},\frac{1}{2}$

Answer 1

Step 1: Convert given fractions into percentages

$\frac{4}{5}=\frac{4\times 20}{5\times 20}=\frac{80}{100}=80\%$

$\frac{3}{10}=\frac{3\times 10}{10\times 10}=\frac{30}{100}=30\%$

$\frac{17}{20}=\frac{17\times 5}{20\times 5}=\frac{85}{100}=85\%$

$\frac{18}{25}=\frac{18\times 4}{25\times 4}=\frac{72}{100}=72\%$

$\frac{1}{2}=\frac{1\times 50}{2\times 50}=\frac{50}{100}=50\%$

Step 2: Arrange the percentages in from larger to lower value

Given percentages can be arranged in descending order as

$85\%,80\%,72\%,50\%,30\%$
