What whole number is equivalent to 8/2

4 is the whole number equivalent.  When dealing with an improper fraction or one that is "top heavy" you take the denominater (the bottom number) unto the numerator.
 Two(2)goes into 8, 4 times, making it whole!

To solve this problem follow the steps below...

Step 1: To turn 8/2 from an improper fraction into a whole number simply divide 8 by 2

8/2=8÷2=4

Step 2(is optional): Check your answer
Since you found the whole number by dividing to check your answer you do the opposite and multiply by 2 instead of dividing by 2

4x2=8

4
