Question: 0.30 is what percent of 21?

Percentage solution with steps:

Step 1: We make the assumption that 21 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\%}={21}.

Step 4: In the same vein, {x\%}={0.30}.

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

{100\%}={21}(1).

{x\%}={0.30}(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{21}{0.30}

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

\frac{x\%}{100\%}=\frac{0.30}{21}

\Rightarrow{x} = {1.4285714285714\%}

Therefore, {0.30} is {1.4285714285714\%} of {21}.
