1/-8-9
show your work using pemdas
To solve the expression using PEMDAS (the order of operations), we follow the steps in the following order:
1. Parentheses: There are no parentheses in the given expression.
2. Exponents: There are no exponents in the given expression.
3. Multiplication and Division (from left to right):
- There are no multiplication or division operations in the given expression.
4. Addition and Subtraction (from left to right):
The given expression is: 1/(-8) - 9
To simplify this expression, first evaluate the division operation:
1/(-8) = -1/8
Now substitute the value back into the expression:
-1/8 - 9
Next, simplify the subtraction operation:
-1/8 - 9 = -1/8 - 9/1
To combine these fractions, we need a common denominator. The common denominator is 8, so we rewrite -9 as -9/1 = -72/8.
-1/8 - 72/8 = (-1 - 72)/8 = -73/8.
Therefore, the simplified expression is -73/8.
To solve the expression 1/-8-9 using PEMDAS (the order of operations), follow these steps:
Step 1: Start with the division operation within the expression.
1/-8 = -1/8
After performing the division operation, the expression becomes:
-1/8 - 9
Step 2: Proceed with the subtraction operation.
-1/8 - 9 = -1/8 - 72/8
After performing the subtraction operation, the expression becomes:
-73/8
Therefore, 1/-8-9 simplifies to -73/8.
