Question

How do you multiply and simplify `-\frac { 2} { 7} ( - \frac { 1} { 4} )`?

Answer 1

`1/14`

Explanation:

When you multiply fractions, you multiply the top numbers and the bottom numbers.
A negative number times a negative number makes a positive number.

Multiply the top :
`(-2)/7 * (-1)/4 = (-2 * -1)/() = 2/()`

Multiply the bottom :
`(-2)/7 * (-1)/4 = (-2 * -1)/(7 * 4) = 2/(28)`

Simplify:
`2/28 -: 2/2 = 1/14`
