Answer: 30
Step-by-step explanation:
40 percent *75 =
(40:100)*75 =
(40*75):100 =
3000:100 = 30
Now we have: 40 percent of 75 = 30
Question: What is 40 percent of 75?
Percentage solution with steps:
Step 1: Our output value is 75.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$75=100\%$.
Step 4: Similarly, $x=40\%$.
Step 5: This results in a pair of simple equations:
$75=100\%(1)$.
$x=40\%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{75}{x}=\frac{100\%}{40\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{75}=\frac{40}{100}$
$\Rightarrow x=30$
Therefore, $40\%$ of $75$ is $30$
