Anwer:
4b/a=2
Explanation:
Lets assume:
a = 4 & b = 2
So a/b would equal 2.
4b/a indicates that you are going to multiply b times 4, meaning that in this scenario you would multiply 2 times 4.
4(2) = 8
and 8 divided by (4) is 2.
Why 4? Because remember a = 4 (in this scenario).
Other examples:
10/5 = 2, --> 4(5) = 20, --> 20/10 = 2.
20/10 = 2. --> 4(10) = 40, --> 40/20 = 2.
