Question

Tom is burning CDs of music he loves. He can burn a CD in 4/5 of an hour. If he has 8 spare hours this week, find 8÷4/5, the number of CDs he can burn in his spare time.

Answer 1

Answer: 10 CD's

Step-by-step explanation:

Given

Tom can  burn a CD in  $\frac{4}{5}\ \text{of an hour}$

If he has 8 spare hours in the week, he can burn

$\Rightarrow 8\div \frac{4}{5}=\dfrac{8}{\frac{4}{5}}\\\Rightarrow \dfrac{8\times 5}{4}=2\times 5=10\ \text{CD}$
