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).

Front

What does it mean to add fractions with the same denominator?

Back

When adding fractions with the same denominator, you add the numerators and keep the denominator the same. For example, 1/8 + 2/8 = (1+2)/8 = 3/8.

Front

What does it mean to subtract fractions?

Back

Subtracting fractions involves taking away the value of one fraction from another. If the fractions have the same denominator, subtract the numerators and keep the denominator.

Front

How do you 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.

Front

What is a mixed number?

Back

A mixed number is a whole number combined with a fraction, such as 1 1/2.

Front

What is an improper fraction?

Back

An improper fraction is a fraction where the numerator is greater than or equal to the denominator, such as 9/4.

Front

How can you convert an improper fraction to a mixed number?

Back

To convert an improper fraction to a mixed number, divide the numerator by the denominator. The quotient is the whole number, and the remainder is the new numerator.

Front

What is the sum of 1/8 and 2/8?

Back

1/8 + 2/8 = 3/8.

Front

What is the result of 11/15 - 2/5?
