Answer 2

Answer:

54

Step-by-step explanation:

So, the first thing we need to do here is set up a proportion: $\frac{40}{100} =\frac{x}{135}$. This is because 40%=40/100, so if 135 was 100%, x would be 40% of that.

To solve the equation, first cross multiply.

$\frac{40}{100} =\frac{x}{135} --> \frac{135*40}{100x}$

$--> 5400=100x$

$x=54$

Checking your work:

40/100= 2/5

54/135= 2/5

This means your answer is correct.
