um could someone help me out with this problem?

Question

Multiply or divide as indicated. Be sure to reduce all answers to lowest terms.

 

a²+5a/3a X 4a^2/a²-4a 

 

please help me understand

Answer 1

[(a² + 5a) / 3a] · [(4a²) / (a² - 4a)]

[a(a + 5) / 3a] · [(4a²) / a(a - 4)]            factor out "a"

[(a + 5) / 3] · [(4a²) / (a - 4)]                 reduce

4a²(a + 5) / 3(a - 4)                               multiply numerators and denominators

 

This cannot be reduced. The 4a² and the 3 can be distributed.
