=3/25=325 or 0.120.12 (if the answer is asked to be in decimal form)

Explanation:

Before answering this type of question you have to change mixed numbers into improper fractions.

4/5 ÷ (6 * 3 + 2)/3 = 20/345÷63+23=203

Then you apply KOF (Keep, Opposite, Flip)
You Keep the 4/545, you put the Opposite sign of division, and you Flip the 20/3203

So, you get this:

4/5 xx 3/20 = (4 * 3)/(5 * 20) = 12/10045×320=43520=12100

Then simplify the fraction by dividing by 44, as 1212 is 3 xx 43×4 and 100100 is 25 xx 425×4; they have a common factor.

The answer will be

12/100 = 3/2512100=325, or 0.120.12
