Question

What has the same value as 40% of 84

Answer 1

Step-by-step explanation:

Percentage solution with steps:

Step 1: Our output value is 84.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$84=100\%$.

Step 4: Similarly, $x=40\%$.

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

$84=100\%(1)$.

$x=40\%(2)$.

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

$\frac{84}{x}=\frac{100\%}{40\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{84}=\frac{40}{100}$

$\Rightarrow x=33.6$

Therefore, $40\%$ of $84$ is $33.6$
