Solution for 0.4 is what percent of 80:

0.4:80*100 =

(0.4*100):80 =

40:80 = 0.5

Now we have: 0.4 is what percent of 80 = 0.5

Question: 0.4 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\%}={0.4}.

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

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

{x\%}={0.4}(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}{0.4}

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

\frac{x\%}{100\%}=\frac{0.4}{80}

\Rightarrow{x} = {0.5\%}

Therefore, {0.4} is {0.5\%} of {80}.

Solution for 80 is what percent of 0.4:

80:0.4*100 =

(80*100):0.4 =

8000:0.4 = 20000

Now we have: 80 is what percent of 0.4 = 20000

Question: 80 is what percent of 0.4?

Percentage solution with steps:

Step 1: We make the assumption that 0.4 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\%}={0.4}.

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

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

{100\%}={0.4}(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{0.4}{80}

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

\frac{x\%}{100\%}=\frac{80}{0.4}

\Rightarrow{x} = {20000\%}

Therefore, {80} is {20000\%} of {0.4}.
