Front

What is the least common multiple (LCM)?

Back

The least common multiple is the smallest multiple that is exactly divisible by two or more numbers.

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

How do you create an equivalent fraction?

Back

To create an equivalent fraction, multiply or divide both the numerator and denominator of the original fraction by the same non-zero number.

Front

What is the process to add fractions with different denominators?

Back

To add fractions with different denominators, first find a common denominator, convert each fraction to an equivalent fraction with that denominator, and then add the numerators.

Front

What is the formula for converting a fraction to an equivalent fraction?

Back

The formula is: (numerator × k) / (denominator × k), where k is any non-zero integer.

Front

How can you determine if two fractions are equivalent?

Back

Two fractions are equivalent if their cross products are equal, meaning that a/b = c/d if and only if a*d = b*c.

Front

What is the significance of the numerator in a fraction?

Back

The numerator indicates how many parts of the whole are being considered, while the denominator indicates the total number of equal parts.

Front

What does it mean to simplify a fraction?
