15/4 x 2/3 = 30/12= 5/2 = 2 and 1/2
4 goes into 36 9 times.. so therefore 3 4ths of 36 is 27
2/3 times 3/4 = 1/2
5/6 x 4/5 is 2/3.
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.
4 can go into 71 seventeen times with 3/4ths left over.
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.
The reciprocal of 3/4 is 4/3
63/4 * 3/5 = 27/4 * 3/5 = 81/20 = 41/20
12 and 3/4.
3/4 = 75%
