how to do fractions such as 4/5 by 3/10?
87765
If "by" means "multiplied by":\n\n4/5 x 3/10 = 12/50 = 6/25 (multiplying numerators and denominators -- then simplifying the fraction)\n\nIf "by" means "divided by":\n\n4/5 div 3/10 = 4/5 x 10/4 = 40/20 = 20 (invert the second fraction and then follow the steps of multiplication)

1. When numerators are the same - the larger denominators are actually the smallest  6/10 - 6/9 - 6/7\n2. ok you do number 2\n3. Different numerators - now we must make the denominators the same - so find the lowest common denom - 20?  now multiply\n4/10= 8/20   3/5 = 12/20  and 9/20\nso 8/20 12/20 and 9/20 ...put them in order - then reduce back down\n4. all are 2's so handle like #1\n5. handle like number 3\n\n8 - only two you have to check as one is a 15 - it's the least - now check the fraction of the two 16's\n\ngood luck

change mixed fractions to proper fractions and then divide,\nwhats so hard?

Two very important things to know:  Anything times 1 is itself, and anything divided by itself equals 1.  So to create equivalent fractions, you can multiply or divide the top and the bottom by the same number without changing it's basic value.\n\nTry 3/4.  Pick any number, say 5.  5/5 is 1 because anything divided by itself is 1.  So, remembering that you can multiply anything by 1, you could multiply 3/4 by 5/5.\n\n3/4 * 5/5 = 15/20.  Now on a calcualor enter 3/4.  It's .75.  Now enter 15/20.  Also .75\n\nTo reduce fractions it works the same way.  Look at 8/12.  2 goes into both 8 and 12, so you can divide top and bottom by 2 without changing the value of the fraction.  8/2 is 4 and 12/2 is 6 so 8/12 is also 4/6.  Now 2 goes into both of those again, so if you do it again 4/2=2 and 6/2=3.  So 8/12 = 4/6 = 2/3.  If you put all of these into a calculator you will get .66666repeating for all 3 of them.

Okay first of all you write it like this...\n(3.5-1.666~)/1.333~\nUsing fractions is easier in this case, so here it is.\n7/2-5/3= 21/6-10/6=11/6 division by a fraction is multiplication by the inverse, so multiply 11/6 by 3/4 and you get 33/24, which can be reduced to 11/8 (eleven-eigths)\n\nBy the way, it's spelled "parenthesis"

10 - 7 = 3\n\ntherefore 3 x 4 (for the 1/4) = 12\n the number is 12

Find the commone denominator, and then convert both fractions into their equivalents using that denominator.  For example, 1/2 can also be written as 2/4, 3/6, 4/8, etc.  Once both fractions have the same denominator, just add the numerators and reduce.\n\nTo add 1/3 + 4/9, the common denominator is 9.  4/9 is already done, so you would just need to change 1/3.  3 goes into 9 3 times, so multiply the top and bottom by 3 (or multiply by 3/3, which is the same as multiplying by 1 - perfectly legal in math :) 1/3 * 3/3 = 3/9\n\nNow you have 3/9 + 4/9 = 7/9 --- this cannot be reduced any further.

you first ahve to convert the whole number to a fraction... 10/1.  then you must make the 2/3 a reciprocal ( reverse it to 3/2).  then you multiply it.  your equation would look like this:   10/1 x 3/2=30/2 reduced to 15

Divide.\n\nFor example, how many twos are in 10?\n\n10/2 = 5\n\n5 twos in 10.\n\nNow let's try to divide 15 by 5/4. Do you know how to divide by a fraction? Invert the fraction and multiply.\n\nSo we get\n\n15 * 4/5 = 12\n\nTo check, we can multiply 5/4 by 12 and see if we get 15.\n\n12 * 5/4 = 15\n\nYes!!!

Sure.  To multiply 3/4 x 1/2, for example, you multiply the numerators (3 x 1) and the denominators (4 x 2) and end up with 3/8.  To divide by 3/4 by 1/2, you invert the multiplier, making it 2/1, and then multiply the numerators (3 x 2) and denominators (4 x 1) and end up with 6/4 or 1 1/2.

7/5.\n\n(2/5)^2 = 4/25, then divide by (1/5) to get 4/5.\n\nAs for the rest, it's (-2) * (-3) / 10 = 6/10 = 3/5.\n\n3/5 + 4/5 = 7/5.

To do this, you do (2/3) / (1/5). You must flip the denomiator fraction over and change the operation to multiplication. So... that would be (2/3) * (5/1) which would be 10/3.
