It all depends on the math question but usually you solve for x, then check it. Plug x back in and see if it works. But it all depends on the math problem
Answer:
Decimal= .75
fraction= 75/100; 3/4
Step-by-step explanation:
A % is out of a hundred, so you don't need the %/100. Then, you wouldn't do cross multiplication, you would just divide 15/27. Remember, it would be 15/27 because it's percent markup, not the percent the price increased by. So, doing that simple calculation on a calculator you get 0.5555. This converted to a percent is just moving the decimal to the right twice, or multiplied by a 100. That would give you 55.55%, and that's your answer. Make sense?
