the answer is: 18
six sevenths times twenty one wholes = 18
One-seventh = 21/7 = 3 so three-sevenths = 3 x 3 ie 9.
1 and 6/7 or 27/7
In order to do this problem, you need to multiply directly. So, 2 over 3 times 6 over 7. First, we're going to do the top. 2 times 6 is 12. The bottom is 3 times 7, which is 21. Your answer is 12 over 21, but they can be both reduced by 3, so your final answer is 4 over 7.
Convert them to a common denominator, which in this case is 35 (5 x 7...the two denominators multiplied), so 3/5 becomes 21/35 and 4/7 becomes 20/35, therefore three fifths is greater than four sevenths.
To convert the improper fraction 6/21 into a mixed number, you divide the numerator (6) by the denominator (21). This division gives you a quotient of 0 with a remainder of 6. Therefore, the mixed number equivalent of 6/21 is 0 6/21 or simply 6/21.
The answer is six
To find out how many two-sevenths are in 6 wholes, we need to first convert the wholes into sevenths. Since there are 7 sevenths in a whole, 6 wholes would be equal to 6 x 7 = 42 sevenths. Next, we divide the total sevenths by the denominator of the fraction we are looking for, which is 7 in this case. So, 42 sevenths divided by 2 sevenths equals 21. Therefore, there are 21 two-sevenths in 6 wholes.
2/7 times 21 = 6
(6 × 7) ÷ 2 = 21
6 divided by 2/7 = 21
2/7 of 21 is 6.
18 / 6/7 = 21
Four sevenths of 21 is 12.
63/7 * 21 = 45/7 * 21 = 45*3 = 135
It is: 119 and 5/7 minus 21 and 6/7 = 97 and 6/7
3 / 1/7 = 3 x 7 = 21 Therefore, there are 21 sevenths in three wholes.
2/3 + 2/7 = 14/21 + 6/21 = 20/21
