80 divided by four equals 20.
Commutative, not communtative The mathematical property of being able to change the order of the numbers and not change the answer. A plus B equals B plus A (1 plus 3 equals 4, 3 plus 1 equals 4) A times B equals B times A (2 times 5 equals 10, 5 times 2 equals 10) Addition and multiplication are commutative operators A minus B is not necessarily equal to B minus A (6 minus 4 equals 2, 4 minus 6 equals minus 2) A divided B is not necessarily equal to B divided A (9 divided by 3 equals 3, 3 divided by 9 equals one-third) Subtraction and division are not commutative operators
Because there is no way to define the divisors, the equations cannot be evaluated.
A/b = 50/88 = 0.5681818181
The answer is 144. The compound operator for (a) and (b) in each pair is a * (a+b). For 9 and 7, this is 9 x (9+7) = 9 x 16 = 144.

4/b-3 + 3/b = -2b/b-3 b = 1 or b = -4.5
b - 4 = 5 Add 4 to both sides: b = 9
4+5=9
Because there is no way to define the divisors, the equations cannot be evaluated.

A/b = 50/88 = 0.5681818181
A:B = 3:4 = 9:12 B:C = 6:5 = 12:10 So A:B:C = 9:12:10
a/b = 1 so a = b. Then a b = q implies that a = b = q/2 So ab = (q/2)*(q/2) = q2/4
The answer is 144. The compound operator for (a) and (b) in each pair is a * (a+b). For 9 and 7, this is 9 x (9+7) = 9 x 16 = 144.
