The simplified form of 7bk-9mn + 5mn + 2bk is 9bk - 4mn.
Because each of the numbers is a multiple of 3, so their product will be a multiple of 3 x 3 = 9. Algebraically: let the two numbers from the 3 times table be 3m and 3n for some m and n. Their product is 3m x 3n = (3 x 3)mn = 9mn, a multiple of 9.

The GCF of 3mn, 9mn, and 12mn is 3mn.
The GCF is 3mn.
Suppose x and y are any two elements of the set.Then x = 3m + 1 and y = 3n + 1 for some integers m and n. Then x*y = (3m + 1)*(3n + 1) = 9mn + 3m + 3n + 1 = 3*(3mn + m + n) + 1. Since m and n are integers, mn+ m + n is also an integer = p, say. Then x*y = 3p + 1. That is the set is closed under multiplication.
The balanced equation for the reaction is: 3Mn3O4 + 8Al -> 9Mn + 4Al2O3. This shows that 3 moles of Mn3O4 produce 9 moles of Mn. Thus, 54.8 moles of Mn3O4 would produce 9 * (54.8/3) = 164.4 moles of Mn atoms.
Because each of the numbers is a multiple of 3, so their product will be a multiple of 3 x 3 = 9. Algebraically: let the two numbers from the 3 times table be 3m and 3n for some m and n. Their product is 3m x 3n = (3 x 3)mn = 9mn, a multiple of 9.
