Find the percent.
3 is what percent of 8?

The word "Per" means 100. To find the percentage of two numbers, you'll multiply the percentage by 100, then divide it by what the "part" is.

Step 1. Multiply the percentage. Like I've said before, we multiply the percentage by 100. The percentage would be 3, if 8 was the percentage, it would be a repeating decimal, which the percent isn't repeating. So, we can multiply 3 by 100.

3 × 100 = 300

Step 2. Divide the part by the percentage. The "part" would be 8, because  if you divide 800 by 3, it will be a repeating decimal. So, we'll have to divide 300 by 8 to get the percentage.

300 ÷ 8 = 37.5

Hence, 37.5 is the answer.

Here are some formulas,

step-by-step explanation:

starting with:    

5 + x - 12 = 2x - 7   

5 + x - 12 - x = 2x - 7 - x (subtract x from both sides)   

5 - 12 = x - 7 (combine and cancel x's from both sides)   

5 - 12 + 7 = x - 7 + 7 (add 7 to both sides)   

0 = x (add numbers together on both sides)       

so in order for the equation to be true, x must be 0.   

trying x = -0.5   

5 + x - 12 = 2x - 7 (original equation)   

5 + -0.5 - 12 = 2(-0.5) - 7 (plug in value of x)   

5 + -0.5 - 12 = -1 - 7 (did multiplication)   

-7.5 = -8 (did addition on both sides)       

since -7.5 is obviously not equal to -8, the value of -0.5 for x is wrong.   

trying x = 0   

5 + x - 12 = 2x - 7 (original equation)   

5 + 0 - 12 = 2(0) - 7 (plug in value of x)   

5 + 0 - 12 = 0 - 7 (did multiplication)   

-7 = -7 (did addition on both sides)       

since -7 equals -7, that demonstrates that the value of 0 for x is correct.   

trying x = 1   

5 + x - 12 = 2x - 7 (original equation)   

5 + 1 - 12 = 2(1) - 7 (plug in value of x)   

5 + 1 - 12 = 2 - 7 (did multiplication)   

-6 = -5 (did addition on both sides)       

since -6 is obviously not equal to -5, the value of 1 for x is wrong.
