Question

30 ÷ (21-6) times 4Find the value of each expression.Order of operations.PEMDAS.

Answer 1

Given the expression:

`30/(21-6)\cdot4`

You need to solve each operation using the order PEMDAS:

- P: Parentheses.

- E: Exponents.

- M and D: Multiplication and Division (from left to right).

- A and S: Addition and Subtraction (from left to right).

Therefore, you need to follow these steps in order to find the value of the expression:

1. Solve the Subtraction inside the parentheses:

`=30/(15)\cdot4`

2. Solve the Multiplication:

`=30/60`

3. Now you have to solve the Division. Notice that you need to divide 30 by 60:

`=0.5`

Hence, the answer is:

`=0.5`
