Answer 1

To evaluate the expression \( (10 - 1)(2)/27 \), we first simplify what is inside the parentheses:

1. Calculate \( 10 - 1 \):
\[
10 - 1 = 9
\]

2. Now substitute this back into the expression:
\[
(9)(2)/27
\]

3. Multiply \( 9 \) by \( 2 \):
\[
9 \times 2 = 18
\]

4. Now divide \( 18 \) by \( 27 \):
\[
\frac{18}{27}
\]

5. Simplifying \( \frac{18}{27} \):
\[
\frac{18 \div 9}{27 \div 9} = \frac{2}{3}
\]

So, the expression evaluates to \( \frac{2}{3} \).

Therefore, the correct response is:

**2 thirds**
