Question

Simplify the following expression(1/5)(-5/7)(2/4)

Answer 1

-1/14

Explanation:

To simplify the expression, you should first divide up the parts to make it easier. Multiply 1/5 by -5/7 first. When you multiply the two fractions, the fives cancel out since there is a five in both the numerator and the denominator. This leaves us with just -1/7.

`(1)/(5) *(-5)/(7) =(-1)/(7)`

Now, multiply -1/7 by 2/4. Notice that you can simplify 2/4 to 1/2. You can't cancel out anything in this expression so simply multiply the two fractions.

`(-1)/(7) *(1)/(2) =-(1)/(14)`

I moved the negative sign from the numerator out front, but you don't have to do that.
