Question

Customers at an ice-cream shop took a survey. The results showed that 144 customers rated the shop as being "very satifactory." This number represented 45% of the total numbers of customers who took the survey
What was the total number of customers who took the survey?

Answer 1

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!!
