Question

I am genuinely lost ..... pls dont give me pdfs or links

There are 25% more 7th graders than 6th graders in band. If there are 135 total 6th and 7th graders in the school band, how many 6th graders are in band?

Answer 1

There are 60 6th graders in band.

Explanation:

Let x represent the number of 6th graders in band. If there are 25% more in 7th grade, you can write it as (5/4)x. (You could also say 1.25x, but I think fractions would be easier in this situation.) Set up an equation:

x+(5/4)x=135

Now solve for x.

(4/4)x+(5/4)x=135

(9/4)x=135

(1/4)x=15

x=60

There are 60 6th graders in band.
