Adding and Subtracting Mixed Numbers

How do you simplify a fraction?

• Multiply the numerator and denominator by their least common multiple.

• Add the numerator and denominator together.

• Divide the numerator and denominator by their greatest common factor.

• Subtract the numerator from the denominator.

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

• Multiply the denominator by the whole number and add the numerator.

• Divide the numerator by the denominator; the quotient is the whole number, and the remainder is the new numerator.

• Subtract the whole number from the numerator and keep the denominator the same.

• Add the numerator and denominator to get the mixed number.

What is an improper fraction?

• A fraction where the numerator is less than the denominator, such as 3/4.

• A fraction where the numerator is equal to the denominator, such as 5/5.

• A fraction where the numerator is greater than or equal to the denominator, such as 9/4.

• A fraction that cannot be simplified, such as 6/8.

What is the importance of understanding mixed numbers in real life?

• Mixed numbers are used in cooking, construction, and other practical applications where whole and fractional quantities are needed.

• Mixed numbers are only used in academic settings and have no real-life applications.

• Mixed numbers are primarily used in financial calculations and budgeting.

• Mixed numbers are irrelevant and can be ignored in everyday life.

Why can't we just add the numerators and denominators of fractions with different denominators?

• Because the fractions must be equivalent.

• Because the numerators must be the same.

• Because the denominators must be added first.

• Because fractions with different denominators are always larger.
