4th Grade Fractions Review

How do you subtract fractions?

• To subtract fractions, they must have a common denominator. If they do not, find a common denominator, convert the fractions, and then subtract the numerators.

• Simply subtract the numerators and keep the denominators the same.

• Multiply the fractions and then subtract the result from one of the fractions.

• Add the fractions together and then subtract the result from one.

What is a unit fraction?

• A fraction where the numerator is 1 and the denominator is a positive integer.

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

• A fraction that equals zero.

• A fraction with a numerator of 0.

How do you simplify a fraction?

• By multiplying the numerator and denominator by their least common multiple (LCM).

• By dividing the numerator and the denominator by their greatest common factor (GCF).

• By adding the numerator and denominator together.

• By subtracting the numerator from the denominator.

How do you decompose a fraction?

• Decomposing a fraction means breaking it down into a sum of unit fractions, such as @@\frac{4}{5} = \frac{1}{5} + \frac{1}{5} + \frac{1}{5} + \frac{1}{5}@@.

• Decomposing a fraction involves multiplying the numerator and denominator by the same number.

• Decomposing a fraction means converting it into a decimal form.

• Decomposing a fraction is the process of finding a common denominator.

What is a proper fraction?

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

• A fraction where the numerator is equal to the denominator.

• Two fractions are equivalent if they have the same numerator and denominator.

• Two fractions are equivalent if their decimal representations are the same.

• Two fractions are equivalent if they can be simplified to the same fraction.

What is the least common denominator (LCD)?

• The largest number that can be used as a common denominator for two or more fractions.

• The smallest number that can be used as a common denominator for two or more fractions.

• The number that is the sum of the denominators of two or more fractions.

• The number that is the product of the denominators of two or more fractions.

How do you compare fractions?
