Question

There are five boys to every nine girls in an introductory engineering course .if there are 364 students enrolled in the course , how many are boys ?

Answer 1

234

Explanation:

So what we know is that

5x+9x= students

This equation is saying that for every 5 boys there are 9 girls

we can then plug in 364 for the number of students and add like terms

This means that 14x=364

this means that x=26

This means that there are 26 sets of 5 boys and 9 girls

this means that there are

130 boys

234 girls
