What is today’s learning objective?

Method: You need to change the mixed number into an improper fraction before you can add them together 1 3 4 + 3 4 = 7 4 + 3 4 = 10 4 = CHECK!! Are the denominators the same? When they are, add the numerators together. 2 2 4 =2 1 2 We can change the answer into a mixed number when the numerator is bigger than the denominator.

Adding Mixed Numbers 𝟓 𝟒 + 𝟓 𝟑 = 𝟏𝟓 𝟏𝟐 + 𝟐𝟎 𝟏𝟐 = 𝟑𝟓 𝟏𝟐 = 𝟐 𝟏𝟏 𝟏𝟐 𝟓 𝟒 Work out: 1 1 4 + 1 2 3 You can add the whole numbers first then the fractions in this case.. but it’s not always easy to deal with the fractions! My suggestion  always change to an improper fraction first! Then give your answer as a mixed number: 𝟓 𝟒 + 𝟓 𝟑 = 𝟏𝟓 𝟏𝟐 + 𝟐𝟎 𝟏𝟐 = 𝟑𝟓 𝟏𝟐 = 𝟐 𝟏𝟏 𝟏𝟐 𝟓 𝟒 𝟓 𝟑

Subtracting Mixed Numbers Work out: 3 5 7 −1 1 2 You can subtract the whole numbers first then the fractions in this case, but this isn’t always easy! My suggestion  always change to an improper fraction first! Then give your answer as a mixed number: 𝟐𝟔 𝟕 − 𝟑 𝟐 = 𝟓𝟐 𝟏𝟒 − 𝟐𝟏 𝟏𝟒 = 𝟑𝟏 𝟏𝟒 = 𝟐 𝟑 𝟏𝟒 𝟐𝟔 𝟕 𝟑 𝟐

To Add/Subtract Mixed Numbers Change the mixed numbers to improper fractions Add/Subtract fractions as usual Change the answer back to a mixed number
