Question

From some petroleum, you can get 30% of paraffin. How much petroleum do you need in order to get 18.75 tons of paraffin?

Answer 1

You would have to do 18.75/30%
=75/4*100/30=125/2 

Answer 2

Answer:

62.5 tons.

Step-by-step explanation:

Let x be the tons of petroleum.

We have been given that we can get 30% of paraffin from some petroleum.

To find the the amount of petroleum we need to figure out x such that 30% of x is 18.75.

We can represent this information in an equation as:

$\frac{30}{100}*x=18.75$

Let us solve for x.

$0.30*x=18.75$

Let us divide both sides of our equation by 0.30.

$\frac{0.30*x}{0.30}=\frac{18.75}{0.30}$

$x=62.5$

Therefore, we need 62.5 tons of petroleum to get 18.75 tons of paraffin.
