Question

Use the properties of real numbers to rewrite the expression. 2/5 * (-7) * 5/2

Answer 1

For this case we have the following expression:

$\frac{2}{5}*(- 7)*\frac{5}{2}$

Using the associative property we can rewrite the expression in the following way:

$(\frac{2}{5}*\frac{5}{2})*(-7)$

Finally, simplifying we have:

$(1) (- 7)$

$-7$
