Question

Fred worked these hours during the week: `8, 4 1/2, 3 3/4, 7 1/2, 4 3/4`. If he is paid $5.15 per hour, how much did he earn?

Answer 1

Fred earns `$146.78` during the week.

Explanation:

As Fred has worked for `8,4 1/2,3 3/4,7 1/2,4 3/4` hours during the week,

total number of hours worked is

`8+4 1/2+3 3/4+7 1/2+4 3/4`

= `8+4+3+7+4+1/2+3/4+1/2+3/4`

= `26+2/4+3/4+2/4+3/4`

= `26+10/4=26+5/2=26+2 1/2=28 1/2` hours

and at `$5.15` per hour

he earns `28xx5.15+1/2xx5.15`

= `28xx5+28xx0.15+2.575`

= `140+4.20+2.575`

= `146.775~=146.78`

Hence Fred earns `$146.78` during the week.
