8 - 6 9/10 =

To solve this problem, we can rewrite 8 as a fraction with a denominator of 10:

\( 8 = \frac{80}{10} \)

Now, we convert the mixed number to an improper fraction:

\( 6 \frac{9}{10} = \frac{(6 \times 10) + 9}{10} = \frac{60 + 9}{10} = \frac{69}{10} \)

Now, we subtract the fractions:

\( \frac{80}{10} - \frac{69}{10} = \frac{80 - 69}{10} = \frac{11}{10} \)

We can convert this improper fraction back to a mixed number:

\( \frac{11}{10} = 1 \frac{1}{10} \)
