Question

1. How many percent of 50 is 10? 2. 20 Is 60% of what number?

Answer 1

Answer:

1. 20%

2. $33.\overline{33}$

Step-by-step explanation:

We can use percentage proportions to find out these answers.

For number one, 10 is what percent of 50, we already know our two values so we can make the equation:

$\frac{10}{50} = \frac{x}{100}$

Using the cross products property, we know that x is $(100\cdot10)\div50$ which is 20.

So 10 is 20% of 50.

For number two, we know a different pair of two numbers now: we know the percent of x, and the percent it is, so the equation can become:

$\frac{20}{x} = \frac{60}{100}$

Again, cross products property tells us that x is $(100\cdot20)\div60$, which is $33.\overline{33}$.

Hope this helped!
