For a simple problem like that one, you can use either long division or short division.
You can also get an answer quickly with a calculator, but that method has two
serious disadvantages:
-- You don't learn how to do it, so if you ever have to find an answer quickly
without a calculator, you're in big trouble. You feel awkward, and you appear
uneducated.
-- You don't learn how to do it, so you have no clue or feeling for what the answer
should be. You're willing to accept anything you see on the calculator, and if you
ever enter the problem into it incorrectly, you blindly accept the answer, which is
wrong, because you don't know any better.
16
To solve this, divide 112 into 784. n = 7
Divide by 2 until you get to 7. 2 x 2 x 2 x 2 x 7 = 112
First you have to think what can I divide 49 and 112 by. Once you've worked that out you have to divide the number that you thought that was right. So then your answer would be 7/16.
84 divide by 112 = 0.75
Divide 112 in half.
Simply divide 112 by 2.
When changing ounces to pounds, you divide by 16. Example: 112 ounces in pounds. Divide 112 by 16 and you will get 7, so the answer is 7 pounds.
112 divide by 4 = 28
2324/112 = 20 and 3/4
Their greatest common factor is 7, so divide both parts by 7. That gives you 11 over 16.
To quarter a number means to divide it by four: 112 / 4 = 28
To get a fraction in its simplest form you need to identify any common factors between the numerator and denominator. In this case, a common factor of 49 and 112 is 7. We can divide top and bottom of 49/112 by 7 to give 7/16. There are no more common factors, so 7/16 is the fraction in its simplest form.
