5/24 i think because the denominator aren't the same so you have to get your lowest common denominator like below, then you multiply your numerator also like below, then your going to flip the fractions because it has the same hole number which is 4 like below, then you could solve the question and then you have your answer 5/24 because you cant reduce it. hope it helped

4 1*3/8*3 4 3/24 4 8/24
- 4 1*8/3*8 - 4 8/24 - 4 3/24
________ ________ ________
5/24

You have to make the denominators in 1/8 and 1/3 the same. Multiply the top and bottom of 1/8 by 3 (denominator of 1/3).
Multiply the top and bottom of 1/3 by 8 (denominator of 1/8).
The answers you get are 3/24 and 8/24.
Do 3/24-8/24. You get -5/24.
Subtract the whole numbers now. 4-4 is 0,so add 0 to -5/24.

The final answer is -5/24.

4 1\8 - 4 1\3
look for the lowest common multiple of 8 and 3 or u can just multiply 8 by 3 which is 24.
41/8 - 41/3 all that divided by 24.
24/8=3, 3*41=123.
24/3=8, 8*41=328.
=> (123 - 328)/24 = -205/24

4 1\8 - 4 1\3



My goodness harley,
You've got 3 answers and they are ALL different. What can you make of that

I haven't actually done your question yet, so lets see if I can't agree with at least one of the other responants.

Now, what you have here is

4 + 1/8 - 4 - 1/3 Be careful here, you have to take away the 1/3 as well as taking away the 4.
If I re-arrange this I get

4 - 4 +1/8 - 1/3 A minus sign always belongs to the number behind it. That is really important to understand and remember.
4-4=0 so we are left with

1/8 - 1/3 Now, if you understand what fractions mean then you will know that 1/8 is smaller than 1/3 [if you are not sure about this then you better post again and I will explain it]
Since 1/3 is bigger than 1/8, you should realize that the answer HAS to be negative. (YOu will just use this as a check when you are finished)

Now, just like the others told you, you need to get a common denominator before you can do the subtraction. That means that the number on the bottom has to be the same!
The multiples of 8 are 8,16,24,32, etc
The multiples of 3 are 3,6,9,12,15,18,21,24,27 etc.
The smallest number that is in both lists is 24. So you have to change both your fractions to 24ths.
Now 8x3=24 so
1/8 becomes 1*3 / 8*3 = 3/24 and
1/3 becomes 1*8 / 3*8 = 8/24
so now you have
1/8 - 1/3 => 3/24 - 8/24 => (3-8) / 24 => -5 /24

So I would vote for Anonymous4338's answer.

Thankyou to all 3 of you for answering. It doesn't matter if you get it wrong sometimes. I want people to get involved.

OMG Harley!! i'm so so sorry, i did not notice the + and - sign.
Ok so (4+1/8) - (4-1/3) all that divided by 24 gives (96+3-96-8)/24 = -5/24.
Once again i'm so so sorry. The correct answer is truly -5/24.
