Concept Recap

A mixed number combines a whole number and a proper fraction, such as $3\frac{1}{4}$ , representing the sum of the whole part and fractional part: $3 + \frac{1}{4} = \frac{13}{4}$ .

You ate 2 whole pizzas and $\frac{3}{4}$ of a third pizza—that's $2\frac{3}{4}$ pizzas.

What to Focus On

Core idea: A mixed number names an amount greater than one using whole units and a fractional part.

Common stuck point: The procedure for mixed numbers is the easy part; the trap is reading $2\frac{3}{5}$ as $2 \times 3/5$ . Asking "Is the amount best read as whole units plus a fraction of one more unit?" first is what keeps a correct-looking calculation from being attached to the wrong concept.

Sense of Study hint: Ask: Is the amount best read as whole units plus a fraction of one more unit?

Worked Examples

Example 1

easy

Add

1\frac{2}{5} + 2\frac{1}{5}

The fractional parts of 1²/₅ and 2¹/₅ — same denominator, add the shaded sections

Answer

3 \frac{3}{5}

First step

Add the whole number parts:

1 + 2 = 3

Full solution

2
Add the fraction parts (same denominator): $\frac{2}{5} + \frac{1}{5} = \frac{3}{5}$ .
3
Combine: $3 + \frac{3}{5} = 3\frac{3}{5}$ .

When adding mixed numbers with like denominators, add the whole numbers and the fractions separately, then combine the results. This works because a mixed number is simply a whole number plus a fraction.
