Decimal: 0.4
Percent: 40 %
Fractions, decimals, and percents are three ways to show parts of a whole. We want to write a fraction as a decimal and as a percent. Let's do these things one at a time.
To write a fraction as a decimal, we divide the numerator by the denominator.
To write a fraction as a percent, we first find an equivalent fraction with a denominator of 100. 2/5=x/100 We multiply 5 by 20 to get 100, so we will also multiply 2 by 20 to get an equivalent fraction.
We found that 25 and 40100 are equivalent fractions. Now we can write the new fraction as a percent by looking at the numerator and adding a percent symbol. 2/5=40/100= 40 %
