Question

7/2% of 420
step by step​

Answer 1

Answer:

Percentage solution with steps:

Step 1: Our output value is 420.

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

Step 3: From step 1 above,$420=100\%$.

Step 4: Similarly, $x=7\%$.

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

$420=100\%(1)$.

$x=7\%(2)$.

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

$\frac{420}{x}=\frac{100\%}{7\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{420}=\frac{7}{100}$

$\Rightarrow x=29.4$
