Answer: 18/7
Explanation: To write a mixed number as an improper fraction, first multiply
the denominator times the whole number, then add the numerator.
So here, we multiply the denominator, 7, times the
whole number, 2, then we add the numerator, 4.
So we have (7 × 2) + 4 or 14 + 4 which is 18.
Finally, we put our new number over our
old denominator and we have our answer, 18/7.
So 2 and 4/7 can be rewritten as the improper fraction 18/7.
