Assuming the question means that Adrianna sleeps for 7.5 h (ie 450 min) and her pulse is 56 (ie. her heart beats 56 times per minute), then

\bg_white \begin{align*} \text{Number of heartbeats while sleeping}\ &= 56\ \text{beats per minute}\ \times 450\ \text{minutes} \\ &= 25,200\ \text{beats} \end{align*}
