12 is what percentage of 80

PIT_PIT [208]

Answer: " 15 % " .

_______________________________

→ " 12 is  15%  of 80 " .

_______________________________

Step-by-step explanation:

_______________________________

12 = (n/100) * 80 ;

12 = (80n) /100 ; Solve for "n:

Note: 80/100 = (80/10) / (100/10) = (8/10) = 0.8 ;

12 = (0.8)n ;

↔ (0.8n) = 12

Multiply each side of the equation by "10" ; to get rid of the "decimal" ;

10 * (0.8n) = 10 * 12 ;

to get:

_______________________________

8n = 120 ;

Divide each side of the equation by "8" ;

to isolate "n" on ONE SIDE of the equation; & to solve for "n" ;

8n/8 = 120/ 8 ;

_______________________________

to get:

_______________________________

n = 15 .

_______________________________

Answer: " 15 % " .

_______________________________

→ " 12 is  15%  of 80 " .
