1 x 91, 7 x 13, 13 x 7, 91 x 1 = 91
x - 30% of x = 91 → 70% x = 91 → x = 91÷ 70% = 130
1 x 91, 7 x 13, 13 x 7, 91 x 1
1 x 91, 7 x 13, 13 x 7, 91 x 1
91 x 91 = 8281
91 x 2.2 = 200.2
7 x 91 = 637
1, 7, 13, 91 (1 x 91, 7 x 13).
1, 7, 13, 91 (1 x 91, 7 x 13).
(4/7) x 91 = 52or... (4 x 91)/7 = 52
1 x 91, 7 x 13.
91 = 13 x 7 80 = 2 x 2 x 2 x 2 x 5 Since 91 and 80 have no factors in common other than 1, the GCF of 80 and 91 is 1.
