A 4

B 4.6

C 1

D 52

Answer 1

(27-32)/9*2
-5/9*2
-0.9*2
-1.1 or C. 1

Answer 2

c. 1

Explanation:

Remember PEMDAS.

Parenthesis. Exponents. Multiplication. Division. Adition and Substraction. As a guide to help you remember the order.

But keep in mind one thing, the MD looks as if multiplication has a priority over division, yet it is not, the M and the D have the same weight to them, so depending on where they are in the operation, you have to do them simultaneously, also, you always read the equation from left to right, so we have as a result:

[27-32]/9*2

-5/9*2 Now, from left to right: -0.56*2=-1.11

None of the answers are -1.11, but the closest one is C. 1
