14/21 * 15/18 = 2/3 * 5/6 = 5/9
15/18 × 12/5 = 2/1 or 2
18/21 x 15 is 12 6/7
27 * 5 / 18 = 15/2 = 7.5
5/12:7/18= (5/12)/(7/18)= (5/12)*(18/7)= 15/14
3 with remainder 14.
the average age is 14-18 or 14-17. other age ranges include 15-17 15-18 15-19 15-20 and 14-20, but the average is 14-18
The Least Common Multiple (LCM) of 15, 14, and 18 is 630.
252 ÷ 18 = 14
mean average = sum of dataset / number of items in dataset = (14 + 18 + 13 + 15) / 4 = 60/4 = 15
18 + 18 + 18 = 36 + 18 = 54 68 - 54 = 14 3 times with 14 remaining
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!
To determine how many times 18 goes into 105, you would perform long division. When you divide 105 by 18, the quotient is 5 with a remainder of 15. This means that 18 goes into 105 exactly 5 times, with 15 left over.
