9 is 3 percent of what number?
To find the number, you can set up the equation: 9 = 0.03x, where x is the unknown number we are trying to find. To isolate x, divide both sides by 0.03: x = 9 / 0.03. Solving this equation gives x = 300. Therefore, 9 is 3 percent of 300.
51 is 170 percent of what number?
Well, isn't that a happy little math problem we have here! To find out what number 51 is 170 percent of, we can set up a simple equation. We divide 51 by 1.70 (which is 170 percent as a decimal) to find that the number is 30. Keep on painting those beautiful mathematical equations, my friend!
What is 11.9 percent of 19.75?
The answer is 2.35025. There are two easy ways to find the answer. Either change the percent into a decimal by moving the decimal two places to the left and then multiplying the decimal by 19.75, or you can set it up as a fraction equation. The equation would look like this. x/19.75 cross-multiplied by 11.9/100. It turns into (19.75x11.9)/100.
16 is 40 percent of what number?
To find the number, you can set up the equation: 0.40x = 16. To solve for x, you would divide both sides by 0.40, which gives you x = 16 / 0.40. Therefore, 16 is 40 percent of 40.
If you have a calculate the original number from a percent increase?
Let's set this equation up. Call the original number No and the number you have N and the percentage increase P. The equation to get the number you have ( N ) is No + No x P = N and we want to solve for No so No ( 1 + P ) = N No = N / ( 1 + P )
