Question

Candice spent 5 1/4 hours doing her homework. Her brother, Ronald, spent 1/2 that number of hours doing his homework. How many hours did Ronald spend on his homework?

Answer 1

Ronald spent 2.63 hours doing hw

Answer 2

Answer:  Ronald spent $2\dfrac{5}{8}$ hours on his homework.

Step-by-step explanation: Given that Candice spent $5\dfrac{1}{4}$ hours doing her homework. Her brother, Ronald, spent half of that number of hours doing his homework.

We are to find the number of hours that Ronald spent on his homework.

Since Ronald spent half of the time as his brother Candice, so the number of hours that Ronald spent on his homework is given by

$H_r=\dfrac{1}{2}\times5\dfrac{1}{4}=\dfrac{1}{2}\times\dfrac{21}{4}=\dfrac{21}{8}=2\dfrac{5}{8}.$

Thus, Ronald spent $2\dfrac{5}{8}$ hours on his homework.
