Front

What is a fraction?

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 add fractions with different denominators?

Back

To add fractions with different denominators, first find the Least Common Denominator (LCD), convert each fraction to an equivalent fraction with the LCD, then add the numerators and keep the denominator the same.

What is the Least Common Denominator (LCD)?

Back

The Least Common Denominator (LCD) is the smallest number that can be a common denominator for two or more fractions.

Front

How do you subtract fractions?

Back

To subtract fractions, ensure they have the same denominator. If not, find the LCD, convert the fractions, then subtract the numerators and keep the denominator the same.

Front

What is an equivalent fraction?

Back

An equivalent fraction is a fraction that represents the same value as another fraction, even though the numerator and denominator may be different.

Front

What is the process to simplify a fraction?

Back

To simplify a fraction, divide both the numerator and the denominator by their greatest common factor (GCF).

What is the sum of 2/3 + 1/2?

Back

The sum of 2/3 + 1/2 is 7/6 or 1 1/6 after finding the LCD and adding.

What is the difference between 5/6 and 1/3?

Back

The difference is 1/2 after finding a common denominator and subtracting.
