Start by placing the decimal number over a power of ten. There is 1 number over the decimal place, so place the decimal number over 10^1 (10), and then add the whole number to the left of the decimal.
Then reduce the fraction of the mixed number.
And then finally, convert the mixed number into an improper fraction by multiplying the denominator (5) by the whole number (10), and add the numerator (4). Place the new numerator (54) over the old denominator (5) to get the final fraction.
