13/4 = 3 1/420/5 = 4
7/7 = 1
Explanation - divide 13 by 4 to get 3 with 1 remainder - so 3 + 1/4
20 divided by 5 is 4
7 divided by 7 is 1

If u divide 13 by 4, u get the quotient as 3,remainder as 1 and the divisor is 4.Thus,13/4=3 1/4
20/5=4
7/7=1
20/5=4
7/7=1

a) 13/4= mixed # 3 1/4 you divide by 4 and find the closest # to 13 which would be 12 subtract the numerator (top # of fraction) from that # found (13-12=1) take that answer and place in numerator using your orginal deminator
b) 20/5=4 because 5*4=20 therefore 20 goes into 5, 4 times.
c)7/7=1 because any # divided by itself is 1.
b) 20/5=4 because 5*4=20 therefore 20 goes into 5, 4 times.
c)7/7=1 because any # divided by itself is 1.

Ok... Well, let's take 13/4.
How many times does 4 go into 13? 3 times. So 4x3 is 12, but you have one left over. Sense 4 can go into 13 3 times, that makes 3 wholes. Keep the denominater the same (4), but make the numerator the amount you have left. 13-12= 1, so it would 1/4. But don't forget the wholes numbers!
13/4= 3 and 1/4
20/5= 4, because 5 equally goes into 20 four times.
7/7= 1 whole, because 7 goes into 7 only once.

13/4 = 3 1/4
4x3 = 12
so we put the 3 on the front.
13-12 = 1
its remained 1 which not divided by 4.
Then we write it as 1/4.
3 + 1/4 = 3 1/4
20/5 = 4
5 x 4 = 20
20-20 = 0
Its remained 0 and we don't need to write this as 0/5, because 0/5 = 0.
7/7 = 1
7x1 = 7
7-7 = 0
same as 20/5
4x3 = 12
so we put the 3 on the front.
13-12 = 1
its remained 1 which not divided by 4.
Then we write it as 1/4.
3 + 1/4 = 3 1/4
20/5 = 4
5 x 4 = 20
20-20 = 0
Its remained 0 and we don't need to write this as 0/5, because 0/5 = 0.
7/7 = 1
7x1 = 7
7-7 = 0
same as 20/5

13/4=3 1/4 [when you divide 13 by 4,the quotient is 4 and the remainder is 1.The quotient is shown as the whole number of the fraction and 1 as the numerator of the fraction part]
20/5=4
7/7=1

Divide 13 by 4.
4 goes into 13 3 times.
3x4 = 12
13 - 12 = 1
13/4 is 3, remainder 1, or 3 1/4
20 divided by 5 is 4, remainder 0.
20/5 = 4
7 divided by 7 is 1, remainder 0.
7/7 = 1
Got the hang of it? Good. Practice, practice, practice!!!

This pretty much wants you to divide through, giving the remainder in form of a fraction.
13/4 = 3 R 1
Since you're dividing by 4, the R1 becomes 1/4
So the answer is 3 1/4
the other two divides evenly, so there's no fraction component. I'll let you handle those.

divide each number and if you get a remainder, put that remainder over the divisor and leave it as a fraction, add it to your quotient and that's your mixed number
13 / 4 = 3R1 = 3 + 1/4 = 3 1/4
20/5 = 4
7/7 = 1
