Data:
Apples = 28
Oranges = 20
Pears = 12

What is the ratio of apples to the total pieces of fruit?
Solving:
 $\frac{apples}{apples+oranges+pears} = \frac{28}{28+20+12} = \frac{28}{60} \frac{\div4}{\div4} \to\:\boxed{\boxed{ratio = \frac{7}{15}}}\end{array}}\qquad\quad\checkmark$

HELP PEOPLE I AGAIN FORGOT EVERYTHING

Answer:

Step-by-step explanation:

Create a proportion

$\frac{x}{12} = \frac{63}{84}$

84 divide by what gives you 12? 7

So divide 63 by 7, and you get 9.

This doesn't work with all of these problems so you can always cross multiply then divide.

12(63) = 756

84(x) = 84x

84x = 756

84x/84 = 756/84

x = 9
