(5)/( (- 1.5 + 9.5)) + (0.4(7 + 11))/( - 0.2 ) \\ = (5)/(8) + (0.4 * 18)/( - 0.2 ) \\ = (5)/(8) + (7.2)/( - 0.2 ) \\ = (5)/(8) - 36 \\ = - (283)/(8)

Answer:

The final answer is

-283/8

Explanation:

Given the expression

5/(-1.5+9.5) + 0.4 (7+11) / -0.2

To solve this problem we need to break down its component in steps

Step one

First Let's solve the items in the bracket

5/8+ 0.4 (18) / -0.2

Secondly let's open up the bracket

5/8+7. 2/-0.2

Step two :

We can still solve for the second fraction by Dividing it accordingly

=5/8+(-36)

=5/8-36

Solving the fraction we have

Lcm= 8

=5-288/8

=-283/8
