Question

At Nathan's birthday there were 16 girls, 10 boys and 9 adults. Find the percentage of: the children that are girls? the children that are boys? all the guests that are adults? all the guests that are girls?

Answer 1

Let's find the required ratios first: to get to the relative percentages, we'll simply have to multiply by 100.

Since there are 16 girls, 10 boys and 9 adults, there are

$16+10+9 = 35$

people in total.

So, the ratio of girls is

$\dfrac{16}{35} \approx 0.4571 = 45.71\%$

The ratio of boys is

$\dfrac{10}{35} \approx 0.2857 = 28.57\%$

The ratio of adults is

$\dfrac{9}{35} \approx 0.2571 = 25.71\%$
