Answer 3

To divide \(-\frac{3}{17}\) by \(-\frac{2}{3}\), you can multiply by the reciprocal of the second fraction.

Here’s how to do it:

\[
-\frac{3}{17} \div -\frac{2}{3} = -\frac{3}{17} \times -\frac{3}{2}
\]

Now, multiply the numerators and the denominators:

\[
= \frac{3 \times 3}{17 \times 2} = \frac{9}{34}
\]

So, \(-\frac{3}{17} \div -\frac{2}{3} = \frac{9}{34}\).

The correct response is:

**9/34**.

Answer 4

To find the product of \(\frac{4}{7}\) and \(-\frac{20}{2}\), we first simplify \(-\frac{20}{2}\):

\[
-\frac{20}{2} = -10
\]

Now we can multiply:

\[
\frac{4}{7} \times (-10) = -\frac{4 \times 10}{7} = -\frac{40}{7}
\]

Next, convert \(-\frac{40}{7}\) to a mixed number:

\[
-\frac{40}{7} = -5 \frac{5}{7}
\]

So the final product is:

**−5 5/7**.

Answer 5

To find the distance from the basement floor to the roof, you can calculate the difference in elevation between the roof and the basement:

1. The elevation of the basement floor is \(-15\) feet.
2. The elevation of the roof is \(37\) feet.

The distance from the basement to the roof is given by:

\[
\text{Distance} = \text{Elevation of the roof} - \text{Elevation of the basement}
\]

Substituting in the values:

\[
\text{Distance} = 37 - (-15) = 37 + 15 = 52 \text{ feet}
\]

So, the correct response is:

**52 feet.**
