Adding
- The pictures above shows how to add fractions using doughnuts. The whole numbers are blue and fractions are red.
- Remember to add the
fractions first and then the whole numbers. Add the
numerators(top numbers) and bring the denominator down.
- All mixed numbers (a whole number and a fraction) can be changed to an improper fraction. You will learn about both, mixed numbers and improper fractions on page 5.
- If
you had 1 ½ doughnuts and you decided to eat 1 whole
doughnut. How many doughnuts would you have left? to
subtract fractions, subtract the smaller fraction from the larger one.
- The
problem will say: 11/2
- 1 = 1/2
- You will have 1/2 of a doughnut left.
