4.2:20*100 =

(4.2*100):20 =

420:20 = 21

Now we have: 4.2 is what percent of 20 = 21

Question: 4.2 is what percent of 20?

Percentage solution with steps:

Step 1: We make the assumption that 20 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\%}={20}.

Step 4: In the same vein, {x\%}={4.2}.

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

{100\%}={20}(1).

{x\%}={4.2}(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{20}{4.2}

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

\frac{x\%}{100\%}=\frac{4.2}{20}

\Rightarrow{x} = {21\%}

Therefore, {4.2} is {21\%} of {20}.

Solution for 20 is what percent of 4.2:

20:4.2*100 =

(20*100):4.2 =

2000:4.2 = 476.19047619048

Now we have: 20 is what percent of 4.2 = 476.19047619048

Question: 20 is what percent of 4.2?

Percentage solution with steps:

Step 1: We make the assumption that 4.2 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\%}={4.2}.

Step 4: In the same vein, {x\%}={20}.

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

{100\%}={4.2}(1).

{x\%}={20}(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{4.2}{20}

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

\frac{x\%}{100\%}=\frac{20}{4.2}

\Rightarrow{x} = {476.19047619048\%}

Therefore, {20} is {476.19047619048\%} of {4.2}.
