Question #8e764

Answer 1

6 points

Explanation:

Set up a ratio or proportion.

`15/100 = ?/40`

`15% = 15/100`

40 = the total just like 100 = the total

15% = the part just like the points scored = the part. so

`15/100 = x/40` now solve for x by multiplying both sides by 40

`(15/100) xx 40 = x/40 xx 40`

`40/40 xx x = x` so

`( 15xx 40)/100 = x`

`600/100 = x`

`6= x`
