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 ]
Ah, what a lovely question! To find out what number 25 percent of is 23, we can set up a simple equation. We can divide 23 by 0.25 (which is 25 percent in decimal form) to find the total number. So, 23 divided by 0.25 equals 92. So, the number you're looking for is 92.

Multiply the number the number by .01 and that is the percent.
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
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

125 is 25% of 500
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.
n/2 + 3 = 21
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.
That depends on what the question is. A percent is just a number. You're asking "How do you solve a number?"
