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.
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
112 ounces is equal to 7 pounds. To convert ounces to pounds, divide the number of ounces by 16 (since there are 16 ounces in a pound).
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.
112/16 = 7
