Answer 4

To multiply fractions together, multiply their numerators together, and multiply their denominators together. Then reduce if necessary.

The rule is:
\( \dfrac{a}{b} \times \dfrac{c}{d} = \dfrac{ac}{bd} \)

Here's an example:
\(\dfrac{4}{7} \times \dfrac{3}{5} = \dfrac{4 \times 3}{7 \times 5}=\dfrac{12}{35}\)

Answer 5

Your example is:

\(- \dfrac{7}{9} \times \dfrac{3}{5} \)

Since you are multiplying a negative number by a positive number, the result will be negative.

Now use the rule of multiplying fractions:

\(= - \dfrac{7 \times 3}{9 \times 5} \)

\(= - \dfrac{21}{45} \)

Since the numerator and denominator are both divisible by 3, reduce:

\(=- \dfrac{3 \times 7}{3 \times 15} \)

Now simplify:

\(=- \dfrac{\cancel3 \times 7}{\cancel3 \times 15} \)

\(=-\dfrac{7}{15} \) This is the final answer.
