Answer: The answer is: " 400 " .
____________________________________________
→ 20% of 400 is 80 .
____________________________________________
Step-by-step explanation:
____________________________________________
20% of "x" = 80 ; Solve for " x " ;
20% = 20/100 ;
= 20 ÷ 100 ;
= 20. ÷ 100 ;
= 0.20 ;
____________________________________________
Note that when dividing by 100 , we move the decimal
point backward (when "dividing") — 2 (two) spaces —
since "100" has 2 (two) "zeros" .
____________________________________________
→ 0.20 = 0.2 ;
____________________________________________
→ (0.2) x = 80 ; Solve for "x" ;
In this case, multiply each side of the equation by "10" ; to get rid of the "decimal value" ; as follows:
→ (10) * (0.2) x = 80 * 10) ;
to get:
→ 2x = 800 ;
Now, divide Each Side of the equation by "2" ;
to isolate "x" on one side of the equation ;
& to solve for "x" ; as follows:
→ 2x / 2 = 800 / 2 ;
→ x = 400 .
____________________________________________
The answer is: " 400 " .
____________________________________________
→ 20% of 400 is 80 .

Answer:
400
Step-by-step explanation:
20% of 400 is 80.
20% × x = 80
Multiply both sides by 100 and divide both sides by 20,.
x = 80 × 100/20
x = 400
