Adding Mixed Numbers

1. Stack up the mixed numbers so the whole numbers and fractions are separated.

2. Add the whole numbers.

3. Find common denominators and add the fractions

​Adding Mixed Numbers

​Some people choose to turn the mixed numbers to improper fractions, add them together, and then turn them back to a mixed number in the end. This is just another option for you to consider!

Another option...

Multiple Choice

$$4\ \frac{3}{8}+7\ \frac{1}{4}$$

• $$11\ \frac{4}{8}$$

• $$11\ \frac{3}{4}$$

• $$11\ \frac{5}{8}$$

• $$\frac{5}{8}$$

Multiple Choice

$$11\ \frac{3}{5}+6\ \frac{4}{15}$$

• $$17\ \frac{2}{3}$$

• $$\frac{13}{15}$$

• $$17\ \frac{13}{15}$$

• $$17\ \frac{7}{15}$$

Multiple Choice

If your answer has an improper fraction, you will need to regroup!

$$9\ \frac{3}{4}+8\ \frac{3}{4}$$

• $$17\ \frac{3}{4}$$

• $$19\ \frac{2}{4}$$

• $$18\ \frac{2}{4}$$

• $$17\ \frac{2}{4}$$

Multiple Choice

If your answer has an improper fraction, you will need to regroup the answer!

$$2\ \frac{6}{8}+5\ \frac{3}{4}$$

• $$8\ \frac{4}{8}$$

• $$7\ \frac{4}{8}$$

• $$8\ \frac{1}{8}$$

• $$7\ \frac{1}{8}$$

1. Stack up the mixed numbers.

2. Subtract the whole numbers.

3. Find a common denominator and subtract the fractions.

​Subtracting Mixed Numbers is the same as Adding!

Multiple Choice

$$4\ \frac{3}{4}-1\ \frac{2}{4}$$

• $$3\ \frac{1}{8}$$

• $$6\ \frac{1}{4}$$

• $$3\ \frac{1}{4}$$

• $$4\ \frac{1}{4}$$

Multiple Choice

• $$5\ \frac{5}{9}$$

• $$1\ \frac{7}{9}$$

Multiple Choice

$$12\ \frac{5}{6}-7\ \frac{1}{3}$$

Hint: you may need to put your answer in simplest form!

• $$6\ \frac{4}{6}$$

• $$5\ \frac{4}{6}$$

• $$5\ \frac{1}{2}$$

• $$6\ \frac{1}{6}$$
