Answer: The correct answer is: " 0.6825 ".

Step-by-step explanation:
_______________________________________________
We are asked to convert: " 68 % " ; to a "decimal" .
_______________________________________________
1) Rewrite: " 68 " ; as a "decimal value" :
" 68 " = 68 +
;
→ " " = 1 / 4 = 1 ÷ 4 = 0.25 . (use calculator).
Or: → " " = "
" ;
→ Find the "?" value:
_______________________________________________
Let us consider the "denominators" ;
→ 4 * (what value) = 100 :
→ 100/ 4 = 100 ÷ 4 = 25 .
So: 4 * 25 = 100;
So, to find the "?" value in the numerator:
→ 1 * 25 = ("?") ;
→ 1 * 25 = 25 ;
_______________________________________________
So, we have:
_______________________________________________
→ " " = "
" ;
Rewrite; and replace the "?" value with our know value: " 25 " :
→ " " = "
" ;
Note that: " " ;
= 25/100 = 25 ÷ 100 = 0.25 . {Use calculator.}.,
Or: 25 ÷ 100 = ? ;
→ When dividing by "100" ; we take the number; and move the decimal point back 2 (two) spaces; since "100" has 2 (two) zeros.
→ 25 ÷ 100 = 25. ÷ 100 = .25;
→ write as: " 0.25" .
_______________________________________________
So: " 68 " = 68 + 0.25 = 68.25 .
As such: " 68 % " = 68.25 % ;
_______________________________________________
Now, we write: " 68.25 % " as a decimal ;
<u>Note</u>: " % " ; or "percent" ; means "per hundred" ; or "parts per hundred" ;
or; "divide by 100" ;
_______________________________________________
So; to write: " 68.25 % " as a decimal ;
→ " 68.25 ÷ 100 " = 0.6825 . {← Use calculator.}.
Or: → 68.2 ÷ 100 = ? ;
→ When dividing by "100" ; we take the number; and move the decimal point back 2 (two) spaces; since "100" has 2 (two) zeros.
→ " 68.25 ÷ 100 " ÷ 100 = .6825 ;
→ write as: " 0.6825 " .

The answer is: " 0.6825 " .
