12L800ml = 12800 ml

x\% \: of \: 12800 = 3200 \\  \frac{x}{100}  \times 12800 = 3200 \\ x =  \frac{3200}{128}\% \\ x = 25\% \:  \: ans...

Step-by-step explanation:

 =  =  =  &gt; \underline\green{Formula \: to \: find \: percentage -  -  &gt; }

percentage =  \frac{given \: value}{total \: value}  \times 100

  =  =  &gt; given \: value \:  = 3200 \: ml \\  =  =    &gt;total \: value \:   =  \: 12 \: litres \: 800 \: ml  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  = 12 \times 1000 + 800 \: ml  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: = 12000 + 800 = 12800 \: ml \\  \\ as \: we \: know \: 1 \: litre \:  = 1000ml.

percentage =  \frac{3200}{12800}  \times 100 =  \frac{320000}{12800 }  = 25\%

==> FEW POINTS TO TAKE CARE WILL FINDING PRCENTAGE :---

a) YOU MUST MULTIPLE THE RATIO OF GIVEN VALUE AND TOTAL VALUE BY 100.

b) IF GIVEN VALUE & TOTAL VALUE CONTAINS UNITS THEN THEY BOTH MUST ME CHANGED TO SAME UNIT OR CONVERTED INTO SAME UNITS TO GET PROPER OR CORRECT ANSWER.

c) IF THE GIVEN VALUE AND TOTAL VALUE DOESN'T CONTAINS UNITS THEN YOU CAN IGNORE THE "b" STEP WRITTEN ABOVE.

d) PRECISE CALCULATION IS MUST TO FIND ACCURATE PERCENTAGE.
