Question

Selma spent9/10 of her allowance on a new backpack. What percent of her allowance did she spend?

Answer 1

Converting fraction to percent is simply dividing the numerator by the denominator then multiplying the answer to 100. Here:

$\begin{gathered} \frac{9}{10}=0.9 \\ 0.9\times100=90 \end{gathered}$

Therefore, 9/10 = 90%.

Selma spent 90% of her allowance on a new backpack.
