When a number includes both whole numbers and fractions 1 1 2 What is it called?
It is called a mixed number 1 1 2
Here are some mixed numbers 5 4 9 2 1 3 3 2 5 2 1 4 1 6 8
How much chocolate?
= Whole chocolate bar
= Whole chocolate bar
If 1 bar contains 4 squares……. = 1 bar of chocolate

2 groups of 2 with 1 remaining. 5 (2 x 2)+1 = 5 = 2
5 = ? 3 4 23 (5 x 4)+3 = 23 = 4 23 = 3 23 ÷ 4 = 5r3 = 5 4 4
Keep the denominator the same. To convert a mixed number to an improper fraction what do you do? (Whole number × Denominator) + Numerator Keep the denominator the same.
