Question

Please help explain questions 3 through 5 please. I really want how to slove it.

Answer 1

For number 3, we have to divide 4 hours by 2 days, so we get

`(4)/(2)=2`

so it is 2 hours per day

if there are 392 students, and 184 are boys. there are 208 girls. So the ratio is

`(184)/(208)=(23)/(26)`

and for number 5 we get that

`(420)/(660)=(7)/(11)`
