ten over twenty-five equals r over twenty

Question

A. 4
B. 5
C. 8
D. 200

Answer 1

To solve this question, we can use cross-multiplication.

Ten over twenty-five can be written as 10/25.

10/25 = r/20

To cross-multiply, we multiply the numerator of the first fraction with the denominator of the second fraction, and vice versa:

10 x 20 = 25r

200 = 25r

To solve for r, we divide both sides by 25:

r = 8

Therefore, the answer is C. 8.
