Mixed Numbers And Improper Fractions

Today in math we learned about Mixed Nimbers and Improper Fractions.
Mixed numbers are when you have a whole number and a fraction of another.
Improper fractions are when your numerator is bigger then you denominator.
6 -> Numerator
--
7 -> Denominator

We also learned how to change improper fractions into mixed numbers. To do that you have to divide the denominator into the numerator and put a fraction for the rest.
Eg. 49/5 = 9 4/5

Also we learned how to change Mixed numbers into Improper fraction. To do that you have to
times the whole number by the denominator and add the numerator to it.
Eg. 5 4/5 = 29/5
