A r= 4 3/4
B r= 4 2/5
C r= 4 4/9
plz helppp
2 1/4 r = 10
9/4 r = 10
r = 10 * 4/9 = ____
THANK YOU
C 4 4/9
To find the value of "r" in the equation 2 1/4r = 10, you need to solve for "r". Here's how you can do it:
Step 1: Write the equation.
2 1/4 r = 10
Step 2: Convert the mixed number 2 1/4 to an improper fraction.
2 1/4 = 9/4
Step 3: Rewrite the equation using the improper fraction.
(9/4) r = 10
Step 4: Isolate "r" by dividing both sides of the equation by the coefficient of "r" (9/4).
r = 10 / (9/4)
Step 5: Invert the denominator of the fraction on the right side and multiply.
r = 10 * (4/9)
Step 6: Simplify the multiplication.
r = 40/9
So, the value of "r" in the equation 2 1/4r = 10 is r = 40/9.
Now, looking at the answer choices you provided, none of them match r = 40/9. Therefore, none of the options (A, B, or C) is correct.
