Question

60% of a is 120% of
b. what is the value of 2a-4b?

Answer 1

The value would be 0.

Explanation:

To find this, start by creating an equation with the top portion of the given.

60%a = 120%b

.6a = 1.2b

Now to find the value of a outright, divide both by .6

a = 2b

Using this fact we can replace a with 2b in the latter portion of the equation.

2a - 4b

2(2b) - 4b

4b - 4b

0
