Asked by Matt
There are 72 boys and 90 girls on a math team. For the next competition, Mr Johnson would like to arrange all the students in equal rows with only girls and only boys in each row. What is the greatest number of students that can be in each row?
Answer: 72 + 90=162
162/2=86

Does your answer make sense?
Answered by

Yes to me it does because you take the total number of people on the team and divide by 2

But you only have 72 boys. Each row has only boys or only girls. So 82 is impossible.

consider that 9 divides both 72 and 90

I am thinking about this a bit more now I don't feel that my answer was right. It can't be 86 if there are 72 boys and 90 girls. I am going to play around with the numbers a bit and then post a different answer.

9 rows with 8 boys each
9 rows with 10 girls each
The greatest number of students that can be in each row would be 18
9 rows with 10 girls each
The greatest number of students that can be in each row would be 18

read the question again carefully.
Only boys or girls in each row. Why did you combine them into rows of 18?

I was wrong. The greatest number of students that can be in each row is 9 because there would be a total of 18 rows.

You can have 4 rows with 18 boys & 5 rows with 18 girls. It doesn't tell you it has to be exactly an amount of rows, but maximum of students in a row....

wouldn't it be 9 because 9x8=72 and 9x10=90.

No 18 is correct because
72: 1,2,3,4,6,8,9,12,(18),24,36,72
90:1,2,3,5,6,9,10,15,(18),30,45,90
that is the only Greatest Common Factor(GCF) of 72 and 90
