Dividing these fractions!?

Question

So I'm stumped. I haven't done this in 3 years, more or less...

6 3/8 (divided by) 2 2/8

All I really need is the answer to this one question, thanks!

Answer 1

51/8 divided by 18/8 is .... 51*1/8 divided by 18*1/8

Refactor... 51/18 divided by (1/8)/(1/8)

so, 51/18. (51 is prime so the fraction can't be reduced further.)

Or, if you prefer, 2 5/6 (36/18 + 15/18)

Answer 2

first make the fractions both improper: 6 3/8 turns into 51/8 (multiply 8 & 6 & add 3 & you'll have numerator; denominator is 8). 2 2/8 turns into 18/8. now you have to multiply by the recipricoal. that'll be 51/8 times 8/18. you can reduce that to 51 times 1/18 by changing the eights to ones. (eight goes into eight one time) then you can reduce 51 to 17 and 18 to 6. (three goes into 51 seventeen times and 18 six times). now you have 17 times 1/6. after mulitplying that's 17/16. to change into a mixed number you divide 16 into 17 and get 1 1/16 as the answer.

try working this all out on a piece of paper so it'll make more sense.

don't just write down the answer cuz on your tests/quizzes you won't know how to do it if you never actually tried to learn it.  

Answer 3

Convert mix number to fraction 6 3/8 = 51/8 and 2 2/8 = 18/8

6 3/8 (divided by) 2 2/8  is now seen as

51/8 (divided by) 18/8

Divide fraction means multiply with its reciprocal

(51/8)(8/18) = 51/18 = 17/6

The answer is 17/ 6 convert to mix number = 2 5/6

Answer 4

I'm not going to give you the answer, but you need to know how to figure this out on your own. take 8*6, + 3 and you have the numerator (top number), but keep the 8. That is the improper fraction form. Now do the same to the other one...

8*2 + 2 = the top number, keep the 8. NOW, invert, or SWITCH the second fraction so the top number is at the bottom, and multiply as usual.

I hope this helps.

Answer 5

51/18

6 3/8 = 51/8

2 2/8 = 18/8

51.................18............. 51

---.divided by..-----.....=.....------...X.....8/18

8...................8................8

  

the 8s cancel out and leave  

51/18

Answer 6

The answer is 3.

Answer 7

6 3/8= 51/8

2 2/8=18/8

51/8 divided by 18/8= 51/8 x 8/18=51/18= 2 15/18= 2 5/6

When dividing fractions, keep the first fraction the same, change division to multiplication, and flip( invert) the second fraction.

Answer 8

6 3/8 is 51/8

2 2/8 is 18 /8

To divide 2 fractions multiply by the reciprocal.

51/8 x 8/18 = 408/144 = 2 120/144

Rationalize the fractional part

2 120/144 = 2 60/72 = 2 30/36 = 2 5/6
