What Are Mixed Numbers?
A mixed number combines a whole number with a fraction!
Like having 2 whole pizzas and 3 slices from another pizza (where each pizza is cut into 8 slices). We'd
write this as \(2\frac{3}{8}\).
How to Add/Subtract Mixed Numbers
1️⃣ Add/subtract the whole numbers separately
2️⃣ Add/subtract the fractions (denominators stay the same!)
3️⃣ Simplify if needed (convert improper fractions to mixed numbers)
Let's Practice Together!
Example 1: Adding Mixed Numbers
Solve: \(3\frac{2}{5} + 1\frac{3}{5} = ?\)
Step 1: Add whole numbers: 3 + 1 = 4
Step 2: Add fractions: \(\frac{2}{5} + \frac{3}{5} = \frac{5}{5}\)
Step 3: \(\frac{5}{5} = 1\), so we add this to our whole number: 4 + 1 = 5
Answer: \(5\)
Example 2: Subtracting Mixed Numbers
Solve: \(4\frac{7}{8} - 2\frac{3}{8} = ?\)
Step 1: Subtract whole numbers: 4 - 2 = 2
Step 2: Subtract fractions: \(\frac{7}{8} - \frac{3}{8} = \frac{4}{8}\)
Step 3: Simplify \(\frac{4}{8}\) to \(\frac{1}{2}\)
Answer: \(2\frac{1}{2}\)
Parent Tips 🌟
- Kitchen Math: Use measuring cups to practice - "If we have 1¾ cups of flour and add 2¼ cups, how much do we have?"
- Pizza Party: Draw pizzas or pies to visualize mixed numbers - coloring in the fractions makes it concrete.
- Step by Step: Encourage your child to solve problems in steps (whole numbers first, then fractions) to avoid feeling overwhelmed.
