1) To solve the first equation, we need to simplify both sides of the equation first.

On the left side:
1.28x / 9.6 = 0.13333x

On the right side:
3.2 / 8 = 0.4

Therefore, the equation 0.13333x = 0.4 can be rewritten as x = 0.4 / 0.13333 = 3.

So, the solution to the first equation is x = 3.

2) To solve the second equation, we need to first simplify both sides of the equation.

On the left side:
112 / 3.5x = 32 / x

On the right side:
3.5 / 2.25 = 1.55556

Therefore, the equation 32 / x = 1.55556 can be rewritten as x = 32 / 1.55556 = 20.5827 (approx.)

So, the solution to the second equation is x = 20.5827.
