Sample questions, answers, and also how to
Question: her friend has actually a bag of marbles, and he tells you that 12 percent of the marbles space red. If there space 72 red marbles. How countless marbles does he have altogether?
Answer: 600 marbles.
How To: In this problem, we recognize that the Percent is 12, and also we are also told that the component of the marbles is red, so we recognize that the part is 72.
So, that way that it have to be the full that"s missing. Here is the method to figure out what the full is:
Part/Total = Percent/100
By utilizing a an easy algebra we deserve to re-arrange ours Percent equation choose this:
Part × 100/Percent = Total
If us take the "Part" and multiply it by 100, and then we division that by the "Percent", we will get the "Total".
Let"s shot it out on our problem around the marbles, that"s very basic and it"s simply two steps! We recognize that the "Part" (red marbles) is 72.
So action one is to just multiply that part by 100.
72 × 100 = 7200
In step two, we take the 7200 and also divide that by the "Percent", i beg your pardon we space told is 12.
So, 7200 separated by 12 = 600
And that way that the total variety of marbles is 600.

Again, it"s the "Total" that"s missing here, and also to find it, we just need to monitor our 2 action procedure as the vault problem.
