Given the expression:
[tex]30\div(21-6)\cdot4[/tex]
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:
[tex]=30\div(15)\cdot4[/tex]
2. Solve the Multiplication:
[tex]=30\div60[/tex]
3. Now you have to solve the Division. Notice that you need to divide 30 by 60:
[tex]=0.5[/tex]
Hence, the answer is:
[tex]=0.5[/tex]
