(7/9) x (4/63) = (1/9) x (4/9) = 4/81
5/7 x 9/10 = 9/14
9 x 3/7 = 9/1 x 3/7 = 9x3/1x7 = 27/7 = 36/7
28/9 x 4/7 = 1 and 7/9
6/7 x 9/9 = 54/63 80/9 x 7/7 = 560/63 54/63 + 560/63 = 614/63
28 = 36 x 7/9 = 36/9 x 7 = 4 x 7
(7/9) x (4/63) = (1/9) x (4/9) = 4/81
1 over x2
5/7 x 9/10 = 9/14
3/5 x 7/9 is 7/15
9 x 3/7 = 9/1 x 3/7 = 9x3/1x7 = 27/7 = 36/7
28/9 x 4/7 = 1 and 7/9
6/7 x 9/9 = 54/63 80/9 x 7/7 = 560/63 54/63 + 560/63 = 614/63
6x-7=8x+9 bring the x over -7=2x+9 take the 9 over -16=2x divide both sides by 2 x=-8
9 x 40 = 360
That's the same as 7/9 x 10/9 = 70/81
5/7 ÷ 7/9 = 5/7 x 9/7 = (5 x 9)/(7 x 7) = 45/49
