Question

if the ratio of A to B is 9 times the ratio of B to A, then A/B could be​

Answer 1

Answer:1/9

Step-by-step explanation: If A = 1

then B is = so A by B = 1/9

Answer 2

Answer:

3

Step-by-step explanation:

1. First lets turn the equation into an algebraic expression: A/B = 9B/A

2. Multiply the A(denominator) from the right and the B(denominator) from the left to get A^2 = 9B^2

3. Take the square root of each side to get A=3B

4. Therefore A/B = 3

(To check lets see A = 27 and B = 9: Whats's A/B = 27/9 = 3, Okay, what's 9B/A = (9*9)/27 = 3, so we have checked that the answer makes sense)
