Add and Subtract Fractions

How do you simplify a fraction?

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

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

• Add the numerator and the denominator together.

• Subtract the numerator from the denominator.

How do you check if a fraction is in simplest form?

• A fraction is in simplest form if the numerator and denominator have no common factors other than 1.

• A fraction is in simplest form if the numerator is greater than the denominator.

• A fraction is in simplest form if it can be expressed as a decimal.

• A fraction is in simplest form if both the numerator and denominator are even numbers.

What is the greatest common factor (GCF)?

• The smallest number that divides two or more numbers without leaving a remainder.

• The largest number that divides two or more numbers without leaving a remainder.

• The sum of all factors of a number.

• The product of the two largest numbers in a set.

What is the result of subtracting a fraction from a whole number?

• To subtract a fraction from a whole number, convert the whole number to a fraction with the same denominator as the fraction being subtracted, then perform the subtraction.

• The result is always a whole number regardless of the fraction.

• Subtracting a fraction from a whole number is not possible.

• The result is the whole number minus the numerator of the fraction.

How do you convert a fraction to a decimal?

• Multiply the numerator by the denominator.

• Add the numerator and denominator together.

• Divide the numerator by the denominator.

• Subtract the denominator from the numerator.

What is the result of 1/2 - 1/4?

• 1/2

• 1/4

• 3/4

• 1/8

What is the process for adding fractions with different denominators?

• Find a common denominator, convert each fraction to an equivalent fraction with that common denominator, then add the numerators and keep the common denominator.

• Add the numerators directly and keep the larger denominator.

• Multiply the denominators and add the numerators without finding a common denominator.

• Convert both fractions to decimals and then add them.

How do you subtract fractions with different denominators?

• Find a common denominator, convert each fraction to an equivalent fraction with that common denominator, then subtract the numerators and keep the common denominator.

• Simply subtract the numerators and denominators separately.

• Multiply the denominators and then subtract the numerators.

• Add the fractions first before subtracting.

What is the importance of finding a common denominator in fraction operations?

• It allows for accurate addition or subtraction of fractions.

• It simplifies the fractions to their lowest terms.

• It helps in converting fractions to decimals easily.

• It makes fractions easier to compare without calculations.

What is the result of adding two fractions with the same denominator?

• You multiply the numerators and denominators.

• You add the numerators and keep the denominator the same.

• You subtract the numerators and keep the denominator the same.

• You add the denominators and keep the numerator the same.
