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

-1/14

Step-by-step 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.

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.

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

yes

step-by-step explanation:

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
