Question

How do you evaluate `\frac{-3}{4}\times \frac{-15}{8}`?

Answer 1

See a solution process below:

Explanation:

To multiply fractions you multiply the numerators over the denominators multiplied:

`(-3)/4 xx (-15)/8 => (-3 xx -15)/(4 xx 8)`

Remember: a negative times a negative gives a positive

`(-3 xx -15)/(4 xx 8) => 45/32`

If necessary, we can convert this to a mixed number as:

`45/32 = (32 + 13)/32 = 32/32 + 13/32 = 1 + 13/32 = 1 13/32`
