To find the percent of 15 out of 60, you have to divide fifteen by sixty.
Then, you multiply your answer by 100. (We do this because 100 percent is a exact amount. 100% of sixty is...well, sixty.)
15 / 60 = 0.25
Now, we can multiply 0.25 by 100:
0.25 * 100 = 25 (basically just moving the decimal two places to the right.)
Next, add a percent sign:
25%, is your answer.
15 is 25% of 60.

Answer:
2
Step-by-step explanation:
Use the formula: change of y over change of x.
When you do that, your systems should look like this:
x1 = 2
y1 = 4
x2 = 6
y2 = 12
After that you plug these number into the corresponding variable.
(12 - 4) / (6 - 2) = 8/4 which equals 2.
