Question

Arnold needs to simplify the expression below. (4.3 x 3+11)/(8.2-0.5x 7):6

Which operation should he perform first?
a. 7/ 6
b. 0.5x 7
c. 8.2-0.5
d. 3+11

Answer 1

To simplify the expression, we need to perform the operation of 8.2 - 0.5x 7 first.

Step-by-step explanation:

To simplify the expression (4.3 x 3+11)/(8.2-0.5x 7):6, we need to follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

According to the given expression, the operation that should be performed first is 8.2-0.5x 7. Multiplication comes before subtraction, so we need to compute 0.5 multiplied by 7 before subtracting it from 8.2.

Therefore, the correct answer is c. 8.2-0.5.
