Fraction Operations Mastery Challenge

This video tutorial covers the four basic operations with fractions: addition, subtraction, multiplication, and division. It explains the need for a common denominator in addition and subtraction, demonstrates borrowing in subtraction, and introduces cross-canceling in multiplication. The video also covers the 'keep change flip' method for division and provides examples for each operation, including working with mixed numbers.

What is the first step when adding fractions?

• Find a common denominator

• Subtract the denominators

• Multiply the numerators

• Convert to mixed numbers

How do you convert an improper fraction to a mixed number?

• Add the numerator and the denominator

• Subtract the numerator from the denominator

• Multiply the numerator by the denominator

• Divide the numerator by the denominator

When adding mixed numbers, what should you do with the whole numbers?

• Add them separately

• Ignore them

• Convert them to improper fractions

• Subtract them

What is the common denominator for 7 and 5?

• 12

• 30

• 35

• 42

What should you do if you cannot subtract the numerators without getting a negative number?

• Convert to improper fractions

• Multiply the fractions

• Borrow from the whole number

• Add the fractions

In multiplication of fractions, what is the purpose of cross-canceling?

• To simplify the fractions before multiplying

• To find a common denominator

• To convert to mixed numbers

• To add the fractions

How do you convert a mixed number to an improper fraction?

• Divide the numerator by the denominator
