Answer:
A fraction with a greater numerator (top number) than denominator (bottom number) is called an improper fraction.
To change a mixed number to an improper fraction:
- Multiply the whole number by the denominator of the fraction and add the numerator of the fraction - place this number as the numerator in the new fraction.
- Copy the denominator of the fraction to the denominator of the new fraction.
