Subtracting a Fraction from a whole number

This video tutorial explains how to subtract a fraction from a whole number by converting the whole number into a fraction, finding a common denominator, creating equivalent fractions, and performing the subtraction. It also covers converting the result into a mixed number.

What is the first step when subtracting a fraction from a whole number?

• Convert the whole number into a fraction by placing it over one.

• Find the least common multiple of the numerators.

• Multiply the fraction by the whole number.

• Add the whole number to the fraction.

How do you find a common denominator for two fractions?

• Subtract the smaller denominator from the larger one.

• Multiply the numerators together.

• Add the denominators together.

• Find the smallest multiple shared by the denominators.

What must you do to maintain equivalent fractions when adjusting the denominator?

• Subtract the same number from both the numerator and the denominator.

• Add the same number to both the numerator and the denominator.

• Multiply both the numerator and the denominator by the same number.

• Only change the numerator.

Once you have a common denominator, how do you perform the subtraction?

• Add the numerators and subtract the denominators.

• Multiply the numerators and divide the denominators.

• Subtract the denominators and keep the numerators the same.

• Subtract the numerators and keep the denominator the same.

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

• Subtract the denominator from the numerator to get the whole number.

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

• Multiply the numerator by the denominator and use the product as the whole number.

• Divide the numerator by the denominator and use the quotient as the whole number.
