Question

What is the ratio fo 10 and c?

Answer 1

Explicación:

the total number of parts in the ratio and then multiply this answer by the original ratio. We want to work out $20 shared in the ratio of 1:3. Step 1 is to work out the total number of parts in the ratio. 1 + 3 = 4, so the ratio 1:3 contains 4 parts in total.

Answer 2

10

and it reads "a is a b as c is a d". The first and fourth terms of an arithmetic proportion are called extremes, while the second and third terms are called means. So let the arithmetic ratio 10: 5 = 8: 4. The terms 10 and 4 (are extreme) and, 5 and 8 (are means).
