The ratio of boys to girls in a school is 4:5. How many boys are in the school if there are 720 students.
1 answer:
Answer: 320 boys
Step-by-step explanation: you would first take the total number (720) and divide it by the total number shown in the ratio (5+4=9)
720/9= 80
You would then take 80 and multiply it by 4 because that is the number representing the boys
80*4= 320
