Question

Find a number such that the ratio of 5/2 to the number is the same as the ratio of the number to 5/8. ​

Answer 1

Answer:

5/4

Step-by-step explanation:

• Let the no. be x, then

5/2 : x = 5/8 : x

5/2*x = 5/8*x

5*5 = 8x * 2x

25 = 16x²                       (cross - multiplication)

25/16 = x²

√25/16 = x

5/4 = x
