Answer: 19/4
Explanation: To write a mixed number as an improper fraction, first multiply the denominator times the whole number and then add the numerator.
So here, we multiply the denominator which is 2 times the whole number, 3, and then we add the numerator. So we have (4 x 4) + 3 which simplifies to 19.
Finally, we put our new number over our old denominator and we have our answer which is 19/4.
So 4 and 3/4 can be rewritten as the improper fraction 19/4.
