During bowling practice, Marley rolled 14 strikes out of 70 attempts.

What percent of Marley’s attempts were strikes?

Let's start by making a fraction.

I'll start by giving a tip for these problems. Whenever you do these problems, the fraction should be written as \(\frac{\text{number}}{\text{total}}\)

Here, we have a known number, 14, which is the number of strikes. Therefore, 14 should be the numerator. If she had 70 attempts, then that means she tried 70 times to bowl. So, 70 would be our denominator, our total. Now we can solve:

\(\frac{14}{70} \implies \frac{14 \div 7}{70 \div 7} \implies \frac{2}{10} \implies 0.2\)

The fraction equals 0.2, but that's not a percentage. To find percentage from a decimal, we multiply by 100, so we get:

\(0.2 \cdot 100 \implies \boxed{20\%}\)

(sorry if i'm not allowed to answer, i'm new.)
