Question

Lisa spends 360 minutes practicing piano every day. What percent of the day does she spend doing piano practice?

• A. $25\%$
• B. $30\%$
• C. $20\%$
• D. $\frac{100}{3}\%$

Answer 1

The correct option is A $25\%$

$60$ minutes $=1$ hr
$360$ minutes $=\frac{1}{60}\times 360=\frac{36}{6}=6$ hrs
$1$ day $=24$ hours
Percent of the day that Lisa spend on piano practice $=\frac{6}{24}\times 100\%=\frac{1}{4}\times 100\%=25\%$
