Answer:

Step-by-step explanation:

Set up a proportion to find how many total students there are [notice how females are on top and totals are on the bottom of the ratios]

$\frac{4}{9}$ = $\frac{396}{x}$ so cross multiply 4x = 396(9) so x = 891, if there are a total of 891 students and you need 1 teacher per 11 students then take 891/11 so you need 81 teachers.

You could set up another proportion 1/11 = x/891

Raymond developed an app for smartphones. During the first week, he had 7,040 downloads from girls and 3 times as many downloads

myrzilka [38]

Answer:

The correct calculation is D. 7,040 × 3, then 21,120 ÷ 8

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of downloads from girls = 7,040

Number of downloads from boys = 3 times as many

Number of boys who downloaded and paid the full version = 1 out of 8

2. Which calculation yields the number of boys who bought the full version of the app?

Number of downloads from boys = 3 * 7,040

Number of downloads from boys = 21,120

Number of boys who downloaded and paid the full version = 21,120/8 = 2,640

The correct calculation is D. 7,040 × 3, then 21,120 ÷ 8
