Answer:
18 students
Step-by-step explanation:
72 boys
90 girls
objective: to arrange in rows with equal number (n) of only boys or girls.
To find the maximum number (n) of boys or girls in each row, you need to find the GCF (Greatest Common Factor) of the numbers 72 and 90, such that n divides both numbers evenly without a remainder.
objective: to arrange in rows with an equal number (n) of only boys or girls.
To find the maximum number (n) of boys or girls in each row, we need to find the GCF (Greatest Common Factor) of the numbers 72 and 90, such that n divides both numbers evenly without a remainder.
We will use two methods to find the GCF of two numbers.
Factorize each number to powers of prime and locate the common factors.
72= 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72
90= 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45 and 90
So the GCF/your answer is 18.
