Example Question #14 : How To Find The Part From The Whole With Percentage
In order to convert numbers to a percent, it is easiest to set up a ratio.
We know that percent is just per-cent or per-100, another way to write this is to divide the number by 100.
We would set up the ratio below with x being the number we are looking for:
Now we cross multiply 25 times x and 12 times 100 to get:
Dividing both sides by 25 will give us the percent.
On the left side the 25's will cancel to give us x, on the right side we may need to do some long division to eventually find that 1200/25 = 48.
