Question

Match each pair of equivalent fractions.

1. -4a/8ab

2. -9b^3/-3a^2b

3. 3a^4/1a^3 b^2

4. 5a^4b/-10a^2

A. 3a/b^2

B. -1a^2b/2

C. 3b^2/1a^2

D. -1/2b

Answer 1

Step-by-step explanation:

(1)
`(-4a)/(8ab)`

Apply exponential property . cancel out 'a'

`(-1)/(2b)`

(2)
`(-9b^3)/(-3a^2b)`

Apply exponential property. In division, subtract the exponents

`(3b^2)/(1a^2)`

(3)
`(3a^4)/(1a^3 b^2)`

Apply exponential property. In division, subtract the exponents

`(3a)/(b^2)`

(4)
`(5a^4b)/(-10a^2)`

Apply exponential property

`(-1a^2b)/(2)`

Answer 2

1 would be D

2 would be C

3 would be A

4 would be B
