Use the properties of operations and rules for multiplying and dividing to solve (9)÷(5-4)×(7-9)×(-5)÷(7-2)

Answer 1

Using the properties of operations and the rules for multiplying and dividing, we can solve (9) ÷ (5-4) × (7-9) × (-5) ÷ (7-2) as follows:

First, we solve the expressions inside the parentheses:

(5-4) = 1
(7-9) = -2
(7-2) = 5

Next, we simplify the division operations:

(9) ÷ 1 = 9
-2 ÷ 5 = -0.4

Finally, we multiply all the results together:

9 × -2 × -5 × -0.4 = 72

Therefore, (9) ÷ (5-4) × (7-9) × (-5) ÷ (7-2) equals 72.
