You can change it to 130-70 and that'll give you 50.

Then just cross out the 0 from the 50 since 13-7 didn't have any zeros. So 5.

Helen [10]

Hey, Melany. To answer this problem, simply set up a proportion: \frac{18.75}{100} = \frac{x}{128}. Now let's solve for x.

- Cross multiply:\frac{18.75*128}{100*x} --> 2400 = 100x

- Isolate x:

\frac{2400}{100} = \frac{100x}{100}

This means that x = 24.

There are 24 9th graders in the band.

I'll teach and give you the answer for you problem (5 2/7 −1 1/2 )∙(1− 14/53 )

Convert mixed numbers to improper fractions 5 2/7 = 37/7:

Convert mixed numbers to improper fractions 1 1/2 = 3/2:

(37/7-3/2) * (1- 14/53
