Hi there!

We can begin by making each fraction have a common denominator:
If we make each have a common denominator of ab, we get:

Simplify:

Multiply both sides by ab:

Move b to the opposite side:

Factor out b:

Divide by (ac - 1):

The answer is actually 164.1 because I learned how to multiply this. :)
1.) 3.5% * 500 = 17.5
2.) 70.0% * 50 = 35.0
3.) 25.0% * 440 = 110.0
4.) 10.0% * 46 = 4.6
Answer: -9
Step-by-step explanation: You are not doing 3(-2) to get -6. That's incorrect. What you are supposed to do is multiply the base which is 3 and then multiply it with -2 so that would 3(3) twice and don't forget the negative in front of the two so that would be -9 as the correct answer. :)
