Back

A fraction represents a part of a whole and is written as 'a/b', where 'a' is the numerator (part) and 'b' is the denominator (whole).

How do you multiply fractions?

Back

To multiply fractions, multiply the numerators together and the denominators together. For example, (a/b) * (c/d) = (a*c)/(b*d).

Front

What is the process to add fractions with different denominators?

Back

To add fractions with different denominators, first find a common denominator, convert the fractions, and then add the numerators. For example, 1/3 + 1/4 = (4/12) + (3/12) = 7/12.

Front

What is the process to subtract fractions?

Back

To subtract fractions, ensure they have the same denominator, then subtract the numerators. For example, 5/6 - 1/3 = (5/6) - (2/6) = 3/6 = 1/2.

Front

How do you divide fractions?

Back

To divide fractions, multiply by the reciprocal of the second fraction. For example, (a/b) ÷ (c/d) = (a/b) * (d/c).

Front

What is the least common denominator (LCD)?

Back

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

Front

What is the greatest common factor (GCF)?

Back

The greatest common factor is the largest number that divides two or more numbers without leaving a remainder.

Front

What does it mean to simplify a fraction?

Back

To simplify a fraction means to reduce it to its lowest terms by dividing the numerator and denominator by their GCF.

Front

What is an equivalent fraction?

Back

Equivalent fractions are different fractions that represent the same value, such as 1/2 and 2/4.

Front

What is the product of 1/2 and 3/4?

Back
