Question: 15 is what percent of 1290?

Percentage solution with steps:

Step 1: We make the assumption that 1290 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\%}={1290}.

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

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

{100\%}={1290}(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{1290}{15}

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

\frac{x\%}{100\%}=\frac{15}{1290}

\Rightarrow{x} = {1.16\%}

Therefore, {15} is {1.16\%} of {1290}.

129000:15 = 8600

Now we have: 1290 is what percent of 15 = 8600

Question: 1290 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\%}={1290}.

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

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

{x\%}={1290}(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}{1290}

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

\frac{x\%}{100\%}=\frac{1290}{15}

\Rightarrow{x} = {8600\%}

Therefore, {1290} is {8600\%} of {15}.
