2/3 X 15 = 30/3 = 10.
2/3 minus 6/10 = 1/15
10. You can either multiply 30 by one-third, or divide 30 by 3. It's the same thing, one way or the other.
Five thirds of eighteen is thirty. There are two ways to find this. One is to multiply 5 (the numerator) by 18, which gives you 90. Then, divide 90 by 3 (the denominator). This gives you 30. The other way is to divide eighteen by 3 to find one third of 18. To find 5 thirds of 18, simply multiply one third of 18 by 5.
The third number could be: 3, 6, 15 or 30
One third is 15 miles; two-thirds is 30 miles; three times two-thirds is 90 miles, or three and two-thirds is 3 x 3 x 15 + 30 = 165 miles.
20
Let's see, one-third of 30 would be 30 divided by three, so two-thirds would be twice that answer...
10 cups is thirty "third-cups". so 30/2 ie 15 "two-third" cups.
2/3 X 15 = 30/3 = 10.
"Of" is the same as "times" so 2/3 * 15 = 2/3 * 15/1 --multiply the numerators together and the denominators together. 15*2 = 30 and 3*1 = 3, so 30/3 = 10.
One third of ninety is equal to 90/3 which equals 30.
2/3 minus 6/10 = 1/15
It is 20, because the denominator 3, is going to be divided into 30. The number '3' goes into 30, 10 times. The numerator, 2, is now going to take 10 and add it twice. Remember, the '/' is the vinculum and it means out of. So 10x2 is 20. Therefore, the answer is 20!
15: 2 15 30 10 _ x __ = __ = __ = 10 3 1 3 1
Two thirds of 30 is equal to 2/3 x 30 = 20.
3/5 x 10/3 = 30/15 = 2
