0.3 x = 84
Multiply the number the number by .01 and that is the percent.
To translate the question into an algebraic expression, we write 90% as 0.9 and create the variable x to represent the number in question. 0.9 * x = 45 x = 45 / 0.9 = 50. To verify, 90% of 50 is 45.
If: 9+x = 3 then x = -6
If the number is 'Q' then the expression is: [ 0.26 Q ]
125 is 25% of 500

Here's another way to ask the question: If you have a number and increase it by 40 percent you get 80. What is the number? Let x be the number you're looking for. Forty percent of the number can be expressed as 0.40x (because 40% = 0.40). The question said that x is increased by 40 percent, which implies addition, so the equation is x + 0.40x = 80 1.4x = 80 x = 80/1.4 = 57.14

A percent equation refers to the process of finding the percent of a quantity. For example, a percent equation for 70 questions correct out of 100 would be 70/100 = .7, or 70%. For any number, the percent is the numerator of an equivalent ratio whose denominator is 100.
If the number is 'Q' then the expression is: [ 0.26 Q ]

n/2 + 3 = 21
For the equation 80% of what number equals 40, the unknown number is 50.
What percent is 328 of 246 can be determined by a math equation. The answer is 133.333 percent. Anytime the number for the percentage is higher than the original number it will be over 100.
