Mixed Number Operations
A mixed number joins a whole number with a proper fraction, like two pizzas and three fifths written as two and three fifths. Counting only the slices makes an improper fraction such as thirteen fifths, so switching between the two forms is the key skill. When you add mixed numbers, add the wholes and the fractions separately, and if the fraction sum passes 1 you carry to the whole. Slide the whole, the numerator, and the denominator and the pie slices show each conversion and that add.
