5/6 of 21 is 17 1/2 or 17.5

3/6 = 1/2 One half of 42 is 21.

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.

6 6ths

5/6ths

1 6ths of 30 is equal to 5

5/6 ÷ 1/3 = 5/2 or 21/2 or 2.5

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.
