Question

Simplify −3/4r + 3 − 5/6r − 6 .

Answer 1

[AI-generated answer — Bot GPT 3.5]

To simplify, we combine like terms.

So, we have:

(-3/4r - 5/6r) + (3 - 6)

To combine the terms with r, we need to find a common denominator. The common denominator for 4 and 6 is 12.

So, we multiply -3/4r by 3/3 to get -9/12r, and multiply -5/6r by 2/2 to get -10/12r.

Now the expression becomes:

(-9/12r - 10/12r) + (3 - 6)

Adding the terms with r, we get:

(-9/12r - 10/12r) = (-19/12r)

Now the expression becomes:

(-19/12r) + (3 - 6)

Subtracting 6 from 3, we get:

(-19/12r) + (-3)

To combine these terms, we find a common denominator of 12, and we multiply -3 by 12/12 to get -36/12.

Now the expression becomes:

(-19/12r) + (-36/12)

Adding these terms, we get:

(-19/12r - 36/12) = -55/12

So, the simplified expression is -55/12.

To simplify the expression -3/4r + 3 - 5/6r - 6, let's combine like terms:

First, combine the r terms:
-3/4r - 5/6r = (-3/4 - 5/6)r

To simplify the coefficients, let's find a common denominator for 4 and 6, which is 12:

(-3/4 - 5/6)r = (-18/12 - 10/12)r

Now, combine the constants:
3 - 6 = -3

So, the simplified expression is:
(-18/12 - 10/12)r - 3

Simplifying further:
(-18 - 10)/12 r - 3 = -28/12 r - 3

Therefore, the simplified expression is -28/12r - 3.

To simplify the given expression:

1. Combine like terms:
The like terms in the expression are −3/4r and −5/6r. To combine them, we need to find a common denominator. The common denominator for 4 and 6 is 12. So we can rewrite −3/4r as −9/12r and −5/6r as −10/12r.

Now, the expression becomes:

−9/12r + 3 − 10/12r − 6

2. Combine the coefficients:
Combine the coefficients of the like terms −9/12r and −10/12r, which gives −19/12r.

Now, the expression becomes:

−19/12r + 3 − 6

3. Simplify further:
Simplify 3 − 6, which equals −3.

Now, the expression becomes:

−19/12r − 3

Therefore, the simplified form of the expression −3/4r + 3 − 5/6r − 6 is −19/12r − 3.
