Question

How many more hours did david use on the computer to play games than to do his homework

Answer 1

That is, He used 2.7 hours more to play video games than to do homework on the computer.

Explanation:

To answer this question, we must calculate the number of hours for games and for homework, just like this

`\begin{gathered} \text{Games} \\ h=45\cdot(24)/(100)=10.8 \\ \text{Homework} \\ h=45\cdot(18)/(100)=8.1 \end{gathered}`

Now, we subtract these values and we are left:

`10.8-8.1=2.7`
