Use proportion to find the answer.

prisoha [69]

Answer

$\boxed {64}$

Detailed Explanation

Let's set up a proportion.

$\frac{3}{4.8} = \frac{40}{x}$

Now that we have set up a proportion we would need to cross multiply.

3*x=3x

40*4.8= 192

Solve for x

$3x=192$

$\frac{192}{3} = 64$

Therefore, the answer would be 64.
