6/7 x 9/9 = 54/63
80/9 x 7/7 = 560/63
54/63 + 560/63 = 614/63
It is 614/63.
6/7
75
LCM of 10 & 16 is 80 so (7 x 8)/80 + (9 x 5)/80 = 56/80 + 45/80 = 101/80 = 1 and 21 over 80
6
4 over 7.
6 over 7 of course !
6/7 + 3/7 = 9/7 or 1 2/7
6/7 = 0.86
4+6/10+7/100 = 467/100 = 4.67
6/7 + 1/3 = 14/21
7/9+5/6 = 29/18
