How do I calculate these division facts and what’s the answer 63 ÷ 7 56 ÷ 7
bixtya [17]

Answer:

63 divided by 7 is 9

56 divided by 7 is 8

Step-by-step explanation:

I don't really know how to explain it, because it's kind of complicated to do it how I answered it. I will try, but what you do is write out the equation using the little line division thing with the divisor and the dividend. First for 63 divided by 7, how many times can 7 go into 6? 0, so put a 0 on top of the 6. Then, minus 6 by 0, which is 6. Then, drop down the 3 in the ones place to where the difference of the subtraction problem is, which of 6. Then, we try to find a product that is 63 or close to 63 in a multiplication problem, and one of those factors has to be 7. 7 x 9 = 63, so put a 9 on top of the 3 at the beginning and minus 63 - 63, which is 0, meaning it has no remainder. Very hard to explain digitally, look up a video for help.
