Solution for 2.1 is what percent of 40:

2.1:40*100 =

(2.1*100):40 =

210:40 = 5.25

Now we have: 2.1 is what percent of 40 = 5.25

Question: 2.1 is what percent of 40?

Percentage solution with steps:

Step 1: We make the assumption that 40 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\%}={40}.

Step 4: In the same vein, {x\%}={2.1}.

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

{100\%}={40}(1).

{x\%}={2.1}(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{40}{2.1}

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

\frac{x\%}{100\%}=\frac{2.1}{40}

\Rightarrow{x} = {5.25\%}

Therefore, {2.1} is {5.25\%} of {40}.

Solution for 40 is what percent of 2.1:

40:2.1*100 =

(40*100):2.1 =

4000:2.1 = 1904.7619047619

Now we have: 40 is what percent of 2.1 = 1904.7619047619

Question: 40 is what percent of 2.1?

Percentage solution with steps:

Step 1: We make the assumption that 2.1 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\%}={2.1}.

Step 4: In the same vein, {x\%}={40}.

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

{100\%}={2.1}(1).

{x\%}={40}(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{2.1}{40}

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

\frac{x\%}{100\%}=\frac{40}{2.1}

\Rightarrow{x} = {1904.7619047619\%}

Therefore, {40} is {1904.7619047619\%} of {2.1}.
