Question

5/7=20/r R=28 Can anyone explain how you get 28

Answer 1

Answer:

Step-by-step explanation:

we are given that these two fractions are equal. however, 20/r is just given in numerators and denominators that are four times as large, even though it is still equal to 5/7. we can tell this because 20 is 4 times larger than 5, which means that R must be 4 times larger than 7, right? YES. so we take 7*4 to get 28.
