Say you're trying to figure out what percentage 3 is of 15.

3/15 = x/100

You would cross multiply so..

3(100) = 15x

Then simplify.

300 = 15x

300/15 = 15x/15

20 = x

Therefore, 3 is 20% of 15.

Explanation:

Here Given Sum to Infinity

$\sf S \infty \ =a_1 \ x \ \dfrac{1}{1-r}$

Identify following

a1 = 2

r = 1/2

Solve:

$\rightarrow \sf S \infty \ =2 \ x \ \dfrac{1}{1-\frac{1}{2} }$

$\rightarrow \sf S \infty \ =4$

The sum of this infinity series is 4
