Question

What is 4/2/7 as an improper fraction

Answer 1

If "4/2/7" is all we have to work with, then PEMDAS rules will save the day. Do the division from left to right.

4/2 becomes 2. Then we have 2/7, a proper fraction. I don't see where an improper fraction would come from in this case.

Answer 2

To make a mixed number an improper fraction, multiply the whole number by the denominator and add the product to the numerator. The denominator remains the same. In this case, 4 is multiplied by 7 to become 28, and plus 2 is 30. Therefore it is 30/7.
