10 percent * 40 =

(10:100)* 40 =

(10* 40):100 =

400:100 = 4

Now we have: 10 percent of 40 = 4

Question: What is 10 percent of 40?

Percentage solution with steps:

Step 1: Our output value is 40.

Step 2: We represent the unknown value with {x}.

Step 3: From step 1 above,{ 40}={100\%}.

Step 4: Similarly, {x}={10\%}.

Step 5: This results in a pair of simple equations:

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

{x}={10\%}(2).

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of bothequations have the same unit (%); we have

\frac{ 40}{x}=\frac{100\%}{10\%}

Step 7: Again, the reciprocal of both sides gives

\frac{x}{ 40}=\frac{10}{100}

= (10/100)*40

= (10*40)/100

= 400/100 = 4

Now we have: 10 percent of 40 = 4

Question: What is 10 percent of 40?

We need to determine 10% of 40 now and the procedure explaining it as such

Step 1: In the given case Output Value is 40.

Step 2: Let us consider the unknown value as x.

Step 3: Consider the output value of 40 = 100%.

Step 4: In the Same way, x = 10%.

Step 5: On dividing the pair of simple equations we got the equation as under

40 = 100% (1).

x = 10% (2).

(40%)/(x%) = 100/10

Step 6: Reciprocal of both the sides results in the following equation

x%/40% = 10/100

Step 7: Simplifying the above obtained equation further will tell what is 10% of 40
