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
