If you convert both numbers into 6ths it is easier to work out. 1 and 1/2 is 9/6ths and 2/3rds is 4/6ths. so, 9/6ths - 4/6ths = 5/6ths.
3/6 + 1/3 = 3/6 + 2/6 = 5/6 5 6ths is your answer
4/6ths plus 1/2 = 9/6ths or: 1 & 1/2
1/3 divided by 1/6 = 2
Yes. One half is 3/6ths and one third is only 2/6ths. In another way, one half is 0.50 and one third is 0.33.....
5/6 x 4/5 is 2/3.
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.
