1 is the GCF, so they have no common factors except 1.
It is: 9/11 of 88 = 72
8 9*8=72 11*8=88
LCD(11, 9, 6) = 198
9/11 + 3/8 = 72/88 + 33/88 = 105/88 = 117/88
(88 ÷ 11) × 9 = 72
The factors of 54 are:1, 2, 3, 6, 9, 18, 27, 54The factors of 88 are:1, 2, 4, 8, 11, 22, 44, 88The common factors are:1, 2The Greatest Common Factor (GCF) is:2
The factors of 88 are:1, 2, 4, 8, 11, 22, 44, 88The factors of 90 are:1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90The common factors are:1, 2The Greatest Common Factor (GCF) is:2
