commutative prperty of addition
The greatest common factor of 52 and 81 is 1
52 = 4 x 13 = 22 x 1381 = 9 x 9 = 34Since 52 and 81 do not have any common prime factor, then 52 x 81 = 4,212 is their LCM. So that the other multiples they have in common are all the multiples of 4,212.
9
27
Justify simply means to show how you can change the way the problem is set up. Example: 9(4x + 5) + 4(2x + 9) = 44x + 81 Distributive Property would be the answer. You have to name the property you that is used to make the sentence true.
The greatest common factor of 52 and 81 is 1
81
29 minus 81 is -52.
52 = 4 x 13 = 22 x 1381 = 9 x 9 = 34Since 52 and 81 do not have any common prime factor, then 52 x 81 = 4,212 is their LCM. So that the other multiples they have in common are all the multiples of 4,212.
The LCM is: 4,212
The factors of 52 are: 1, 2, 4, 13, 26, 52 The factors of 70 are: 1, 2, 5, 7, 10, 14, 35, 70 The factors of 81 are: 1, 3, 9, 27, 81
1
81-52 equals = 29
commutative property of multiplication
Yes, they are relatively prime.
Divide 81 by 70%. ===> That is, solve the problem: (81) / (0.7)
