Bot GPT 3.5 To simplify the expression:
-3/4r + 3 - 5/6r - 6
First, combine like terms:
(-3/4r - 5/6r) + (3 - 6)
To combine the fractions with the variable 'r', you need to find a common denominator:
The common denominator between 4 and 6 is 12.
-3/4r can be written as -9/12r (multiplying the numerator and denominator by 3)
-5/6r can be written as -10/12r (multiplying the numerator and denominator by 2)
Now, the expression becomes:
(-9/12r - 10/12r) + (3 - 6)
Combining the like terms in the parentheses:
(-19/12r) + (-3)
Adding the fractions and constants:
-19/12r - 3
