2/5 of 45 = 18
The GCF is 2.
the answer is 18 u just need to multiply to check the 2 and 9 can go into the 18
The factors of 18 are: 1 2 3 6 9 18 The prime factors are: 2 x 3 x 3
The GCF of 18, 20, and 32 is 2. Factors of 18... 1,2,3,6,9 & 18 Factors of 20... 1,2,4,5,10 & 20 Factors of 32... 1,2,4,8,16 & 32... Therefore the GCF would be 2 !
18
-2 > -18 -18 < -2
2/9 × 18 = (2×18)/9 = 36/9 = 4 Alternatively, cancelling as you go: 2/9 × 18 = (2×18)/9 = 2×(18/9) = 2×2 = 4
To find one-ninth of 18, you would divide 18 by 9. Mathematically, 18 ÷ 9 = 2. Therefore, one-ninth of 18 is 2.
20, is the sum of 18 and 2.
LCM of 2 6 and 18 is 18.
9
18
18-2 = 16
5/6 + 2/18 = 15/18 + 2/18 = 17/18
The Least Common Multiple (LCM) for 2 18 3 is 18
Since 2 is a factor of 18, it is automatically the GCF.
