Question: 2.5 is what percent of 80?

Percentage solution with steps:

Step 1: We make the assumption that 80 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\%}={80}.

Step 4: In the same vein, {x\%}={2.5}.

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

{100\%}={80}(1).

{x\%}={2.5}(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{80}{2.5}

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

\frac{x\%}{100\%}=\frac{2.5}{80}

\Rightarrow{x} = {3.125\%}

Therefore, {2.5} is {3.125\%} of {80}.

Solution for 80 is what percent of 2.5:

80:2.5*100 =

(80*100):2.5 =

8000:2.5 = 3200

Now we have: 80 is what percent of 2.5 = 3200

Question: 80 is what percent of 2.5?

Percentage solution with steps:

Step 1: We make the assumption that 2.5 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\%}={2.5}.

Step 4: In the same vein, {x\%}={80}.

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

{100\%}={2.5}(1).

{x\%}={80}(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{2.5}{80}

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

\frac{x\%}{100\%}=\frac{80}{2.5}

\Rightarrow{x} = {3200\%}

Therefore, {80} is {3200\%} of {2.5}.
