A percent is a rate that compares a part to a whole. The second term in the rate is always 100.
70 %
Practice makes perfect
We are given a square divided into 10 equal parts.
We want to write the percent of the figure that is shaded. We will start by recalling that a percent is a rate that compares a part to a whole. The second term in the rate is always 100. We can see that 7 out of 10 parts of the model are shaded. Let's write this information as a rate.
7/10
We want to write this fraction as a percent. We can do this by finding an equivalent fraction with a denominator of 100.
7/10=x/100
Since 10 * 10 is equal to 100, we will multiply the numerator and denominator by 10 to get an equivalent fraction.
We got that 710 and 70100 are equivalent fractions. Now we can write the new fraction as a percent by looking at the numerator and adding a percent symbol.
7/10=70/100= 70 %
We found that 70 % of the figure is shaded.
