Question: 15 is what percent of 2.8?

Percentage solution with steps:

Step 1: We make the assumption that 2.8 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\%}={2.8}.

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

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

{100\%}={2.8}(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{2.8}{15}

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

\frac{x\%}{100\%}=\frac{15}{2.8}

\Rightarrow{x} = {535.71428571429\%}

Therefore, {15} is {535.71428571429\%} of {2.8}.

Solution for 2.8 is what percent of 15:

2.8:15*100 =

(2.8*100):15 =

280:15 = 18.666666666667

Now we have: 2.8 is what percent of 15 = 18.666666666667

Question: 2.8 is what percent of 15?

Percentage solution with steps:

Step 1: We make the assumption that 15 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\%}={15}.

Step 4: In the same vein, {x\%}={2.8}.

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

{100\%}={15}(1).

{x\%}={2.8}(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{15}{2.8}

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

\frac{x\%}{100\%}=\frac{2.8}{15}

\Rightarrow{x} = {18.666666666667\%}

Therefore, {2.8} is {18.666666666667\%} of {15}.
