Questions & Answers

Q: How do you add fractions with the same bottom number?

To add fractions with the same bottom number, simply add the top numbers and keep the bottom number the same. For example, 1/8 + 3/8 = 4/8, which simplifies to 1/2.

Q: What should you do when adding fractions with different bottom numbers?

When adding fractions with different bottom numbers, find a common bottom number by using equivalent fractions. Multiply both the top and bottom numbers of each fraction by factors that will make the bottom numbers the same. Then, add the top numbers together and keep the common bottom number.

Q: How do you add mixed numbers?

To add mixed numbers, first convert them into improper fractions. Then, make the bottom numbers the same using equivalent fractions. Finally, add the top numbers and keep the common bottom number.

Q: How do you subtract fractions or mixed numbers?

Subtraction follows a similar process to addition. For fractions, subtract the top numbers and keep the bottom number the same. For mixed numbers, convert them into improper fractions, subtract the top numbers, and keep the bottom number the same.
