The total number of customers who took the survey was 320. You can write it out like this :
45 144
—- = ——
100 ?
Then you can cross multiply (144 x 100 = 14,400) then divide that answer by 45 (14,400 \ 45 ) The answer you get it 320!!
So 6 is to 9
6:9
16 is to x
16:x
they are eual so change to fraction and solve
6/9=16/x
multiply both sides by x
6x/9=16
multil yboth sides y 9
6x=144
divide by 6
x=24
answer is 24 hours
