Answer 1

no letters.

Answer 2

LEFR AND FRAC AND RIGHT HAVE LETTERS IN THEM DONT THEY? (18 - 8) + \left(-9 \frac{4}{9} + \frac{7}{9}\right) but lesss complex please

Answer 3

thanks you

Answer 4

To make the expression \(18 - 9 \frac{4}{9} + \frac{7}{9} - 8\) easiest to add, we should group it in a way that allows for straightforward calculation of whole numbers and fractions.

The most logical grouping would be:

\[
(18 - 8) + \left(-9 \frac{4}{9} + \frac{7}{9}\right)
\]

This simplifies as follows:

1. **Calculate the whole numbers first: \(18 - 8 = 10\)**
2. **Then deal with the fractions:**

Convert \(9 \frac{4}{9}\) to an improper fraction:
\[
9 \frac{4}{9} = 9 + \frac{4}{9} = \frac{81}{9} + \frac{4}{9} = \frac{85}{9}
\]

Now, substitute into the fraction calculation:
\[
-\frac{85}{9} + \frac{7}{9} = -\frac{85 - 7}{9} = -\frac{78}{9} = -\frac{26}{3} \text{ (if needed)}
\]

Finally, combine your results:
\[
10 + \left(-\frac{26}{3}\right)
\]

Thus, a clear and efficient grouping of the original expression is:

\[
(18 - 8) + \left(-9 \frac{4}{9} + \frac{7}{9}\right)
\]

This makes it easy to compute both parts separately.

Answer 5

Apologies for the confusion. Here’s the answer without letters:

To make the expression \( 18 - 9 \frac{4}{9} + \frac{7}{9} - 8 \) easiest to add, you should group it as follows:

\[
(18 - 8) + \left(-9 \frac{4}{9} + \frac{7}{9}\right)
\]

This means calculating:

1. **Whole numbers**: \( 18 - 8 = 10 \)
2. **Fractions**: \( -9 \frac{4}{9} + \frac{7}{9} = -\frac{85}{9} + \frac{7}{9} = -\frac{78}{9} \)

So in terms of grouping, the best option is:

\[
(18 - 8) + \left(-9 \frac{4}{9} + \frac{7}{9}\right)
\]

This makes it easier to add.

Answer 6

I apologize for misunderstanding your request. Here’s a simpler way to present the grouping without using any letters or complex symbols:

**Best grouping:**

(18 - 8) + (-9 4/9 + 7/9)

**Calculation steps:**

1. Calculate (18 - 8):
- Result = 10

2. Calculate (-9 4/9 + 7/9):
- Convert -9 4/9 to an improper fraction: -9 4/9 = -85/9
- Then, -85/9 + 7/9 = -78/9 = -26/3 (optional)

So the easiest way to group for addition is:

(18 - 8) + (-9 4/9 + 7/9)
