Step-by-step explanation:

12.5 percent *80 =

(12.5:100)*80 =

(12.5*80):100 =

1000:100 = 10

Now we have: 12.5 percent of 80 = 10

Question: What is 12.5 percent of 80?

Percentage solution with steps:

Step 1: Our output value is 80.

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

Step 3: From step 1 above,$80=100\%$80=100%.

Step 4: Similarly, $x=12.5\%$x=12.5%.

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

$80=100\%(1)$80=100%(1).

$x=12.5\%(2)$x=12.5%(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

$\frac{80}{x}=\frac{100\%}{12.5\%}$

80

x=

100%

12.5%

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{80}=\frac{12.5}{100}$

x

80=

12.5

100

$\Rightarrow x=10$⇒x=10

Therefore, $12.5\%$12.5% of $80$80 is $10$10
