question
a recent poll concluded that 63 out of 100 u.s. adults get less than 8 hours of sleep per night. write this ratio as a percent.
provide your answer below:

Explanation:

Step1: Use the formula for percentage

The formula for percentage is $\frac{\text{part}}{\text{whole}}\times100\%$. Here, the part is $63$ and the whole is $100$.
$$\frac{63}{100}\times100\%$$

Step2: Simplify the expression

When we calculate $\frac{63}{100}\times100\%$, the $100$ in the numerator and denominator cancel out.
$$\frac{63\times100\%}{100}=63\%$$

Answer:

$63\%$
