Step-by-step explanation:

30/15 = 2

100/2 = 50

Answer 2

( 15*100):30 =

1500:30 = 50

Now we have: 15 is what percent of 30 = 50

Question: 15 is what percent of 30?

Percentage solution with steps:

Step 1: We make the assumption that 30 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=30$.

Step 4: In the same vein, $x\%=15$.

Step 5: This gives us a pair of simple equations:

$100\%=30(1)$.

$x\%=15(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{30}{15}$

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{15}{30}$

$\Rightarrow x=50\%$

Therefore, $15$ is $50\%$ of $30$.
