Convert the fraction from improper to mixed
Start by dividing the numerator by the denominator
Arrange the numbers for long division
4 goes into 27 six times. So write 6 above the line.
Multiply 6 to 4 and write the answer below 27
Subtract 24 from 27 and write the answer one line below
Since 4 cannot go into 3 anymore, 3 is left as the Remainder and 6 is the Quotient
Substitute values into the given formula
