First, take three off it, because that will form the whole-number part: 3.92 = 3 + 0.92
Next, read off the place value of the last digit. The 2 is in the 'hundredths' column, which means that 0.92 = 92/100: 3.92 = 3 + 92/100
Finally, simplify 92/100 by dividing top and bottom by 4 to get 23/25. Then, shove it all together: 3.92 = 3 23/25
0.92 ;
To convert 3.92 into a mixed number, separate the whole number part (3) from the decimal part (0.92), which is equivalent to 100 92 . Simplify 100 92 to get 25 23 , leading to the final mixed number of 3 25 23 .
