Topic 9 Dividing Unit Fractions

How do you add fractions with different denominators?

• Find a common denominator, convert the fractions, and then add the numerators.

• Add the numerators directly and keep the larger denominator.

• Multiply the denominators and add the numerators.

• Subtract the smaller fraction from the larger one.

How do you divide a fraction by a whole number?

• Multiply the numerator of the fraction by the whole number.

• Multiply the denominator of the fraction by the whole number.

• Add the whole number to the fraction.

• Subtract the whole number from the fraction.

What is a unit fraction?

• A fraction where the numerator is 1 and the denominator is a positive integer, such as @@\frac{1}{2}@@ or @@\frac{1}{5}@@.

• A fraction where the numerator is greater than the denominator.

• A fraction that equals one.

• A fraction with a numerator of 0.

What is the reciprocal of a fraction?

• The reciprocal of a fraction is obtained by flipping the numerator and denominator.

• The reciprocal of a fraction is obtained by adding the numerator and denominator.

• The reciprocal of a fraction is obtained by multiplying the numerator and denominator by 2.

• The reciprocal of a fraction is obtained by subtracting the numerator from the denominator.

What is the process of multiplying fractions?

• To add the numerators and denominators together.

• To multiply the numerators together and the denominators together. For example, @@\frac{1}{2} \times \frac{3}{4} = \frac{1 \times 3}{2 \times 4} = \frac{3}{8}@@.

• To divide the numerators and denominators separately.

• To find a common denominator before multiplying.

What is the relationship between division and fractions?

• Division can be represented as a fraction, such as @@\frac{2}{3}@@.

• Fractions are always greater than division results.

• Division cannot be expressed in terms of fractions.

• Fractions are a type of division that only applies to whole numbers.

How do you find a fraction of a whole number?

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

• Add the numerator and denominator of the fraction to the whole number.

• Subtract the denominator from the whole number and multiply by the numerator.

• Divide the whole number by the numerator and multiply by the denominator.

How do 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 over the original denominator.

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

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

How do you convert a division problem into a fraction?

• Write the first number as the denominator and the second number as the numerator.

• Write the first number as the numerator and the second number as the denominator.

• Multiply the two numbers together to get a fraction.

• Add the two numbers to form a fraction.

What is a mixed number?

• A whole number combined with a fraction, such as 1 @@\frac{1}{2}@@.

• A number that is only a fraction, like @@\frac{3}{4}@@.

• A decimal number that represents a part of a whole, like 0.75.

• A number that is the sum of two whole numbers, like 2 + 3.
