9 2/7 - 6 5/7 = (8 + 1 + 2/7) - 6 5/7 = (8 + 7/7 + 2/7) - 6 5/7 = 8 9/7 - 6 5/7 = 2 4/7
Alternatively, using improper fractions:
9 2/7 - 6 5/7 = (9x7+2)/7 - (6x7+5)/7 = 65/7 - 47/7 = 18/7 = (2x7+4)/7 = 2 4/7

What is 7 over 9 divided by 3 over 6?
So the problem is 7/9 divided by 3/6. you can reduce 3/6 to 1/2 so now your equation is 7/9 divided by 1/2 you do the reciprocal and you get 7/9 multiplied by 2/1 and you get 14/9, or 1 5/9
What number when divided by one will you have a remainder of one when divided by 2 3 4 5 6 7 8 or 9?
(2 x 3 x 4 x 5 x 6 x 7 x 8 x 9) + 1 will have a remainder of 1 when divided by 2, 3, 4, 5, 6, 7, 8, or 9. (2 x 3 x 4 x 5 x 6 x 7 x 8 x 9) + 1 = 362,881
