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