18 12ths= 9 6ths= 3 halves or 3 over 2= 1.5
yes
12 and 5/6ths converts to 12 and 10/12ths. So 12 and 10/12ths - 7 and 5/12ths = 5 and 5/12ths
4/12 is less than 4/6 4/6 = 8/12 so is twice as big as 4/12
5/6 is the same as 10/12 so it is bigger
4
2/3
Yes.
4/6ths plus 1/2 = 9/6ths or: 1 & 1/2
You have to find the common denominator for the fractions, so multiply the "half" (2) by the "thirds" (3). These two numbers multiplied with give 6 as a common denominator. Then multiply the 1 by the 3, which will give 3/6ths, and the 2 by the other 2, which will give 4/6ths. Hmmm! it seems that 4/6ths is greater than 3/6ths, so you have to add a whole to the 3/6ths to make a big enough fraction to subtract. Doing that will give you 9/6ths and you can subtract the 4/6ths. So the answer would be 5/6ths. Try it.
Some fractions that are equal to this include: 10 12ths, 15 18ths, 20 24ths and 40 48ths
