15/18 × 12/5 = 2/1 or 2
18/21 x 15 is 12 6/7
18
5/12:7/18= (5/12)/(7/18)= (5/12)*(18/7)= 15/14
18/11 x 5/12 is 15/22
Well, darling, 17 over 18 minus 2 over 3 is the same as 17 times 3 minus 2 times 18, all over 18 times 3. So, that gives you 51 minus 36 over 54, which simplifies to 15 over 54, or 5 over 18. Math doesn't have to be a drag, honey!
it is 18/18 wich = {1}3/15 + 12/18 = 3/15 + 2/3 = 3/15 + 10/15 = 13/15
14/21 * 15/18 = 2/3 * 5/6 = 5/9
10/12 15/18 20/24 ect...10/12, 15/18, 20/24
Expressed as a proper fraction in its simplest form, 3/15 + 12/18 = 13/15 or thirteen fifteenths. Expressed as a decimal, this is equal to 0.86 recurring (that is, 0.86666...)
3 + 3 = 6 6 x 3 = 18 18 - 3 = 15 15 + 3 = 18
It is: (15+18)+12 = 45
27 * 5 / 18 = 15/2 = 7.5
