Answer:
4/1
Step-by-step explanation:
u put it over 1. Any whole number over one is considered a fraction, but its still the same number.
Multiply both the numerator and denominator by the value you chose in step 2. So to turn the whole number 4 into halves, you would multiply 4/1 by 2/2 and reach a value of 8/2. This completes the conversion of the whole number four into a fraction.
