3 / 1/7 = 3 x 7 = 21 Therefore, there are 21 sevenths in three wholes.
3/7 x 21 = 9

3/7 of 63 is 27.
yes same
3/7 + 8/21 = 9/21 + 8/21 = 17/21
Four sevenths of 21 is 12.
One-seventh = 21/7 = 3 so three-sevenths = 3 x 3 ie 9.
To divide by a fraction, multiply by its reciprocal. In this instance, 3/7 / 4/7 = 3/7 x 7/4 = 21/28 = 3/4. Therefore, three sevenths divided by four sevenths is equal to three quarters.
63/7 * 21 = 45/7 * 21 = 45*3 = 135
