Question

Use properties of real numbers to rewrite the expression.
2/5x(-7)x5/2

Answer 1

Using properties of real numbers, we can rewrite the expression as:

(2/5) (-7) (5/2) = (-7) (2/5) (5/2)

Now, let's simplify each part separately.

(-7) (2/5) = -14/5

And,

(5/2) = 5/2

So, the expression simplifies to:

(-14/5) (5/2) = -14/2

Thus, the simplified expression is:

-14/2 = -7
