Evaluate. r-s/9 for r= 26 and s =8 Simplify your answer
The Correct Answer and Explanation is:
To evaluate the expression r−s9\frac{r – s}{9}9r−s where r=26r = 26r=26 and s=8s = 8s=8, we follow these steps:
Step 1: Substitute the values of rrr and sss
We know that r=26r = 26r=26 and s=8s = 8s=8, so substitute these values into the expression:r−s9=26−89\frac{r – s}{9} = \frac{26 – 8}{9}9r−s=926−8
Step 2: Simplify the numerator
Now, simplify the expression in the numerator:26−8=1826 – 8 = 1826−8=18
So the expression becomes:189\frac{18}{9}918
Step 3: Divide
Now, divide the numerator by the denominator:189=2\frac{18}{9} = 2918=2
Final Answer:
The value of r−s9\frac{r – s}{9}9r−s when r=26r = 26r=26 and s=8s = 8s=8 is 2.
Explanation:
The expression r−s9\frac{r – s}{9}9r−s is a simple arithmetic problem that involves subtraction and division. First, we substitute the given values of rrr and sss into the expression. Then, we perform the subtraction in the numerator, followed by the division by 9. The process involves basic arithmetic steps, and after simplifying, we find that the final result is 222.
This type of problem is useful for understanding how to perform operations within fractions and helps in building foundational skills in algebra.
