What does it mean to add fractions with different signs?

Back

When adding fractions with different signs, you subtract the absolute values of the fractions and keep the sign of the fraction with the larger absolute value.

Front

How do you multiply fractions?

Back

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

Front

What is the result of multiplying a positive fraction by a negative fraction?

Back

The result is negative. For example, (3/4) x (-2/3) = -1/2.

Front

What is the result of multiplying two negative fractions?

Back

The result is positive. For example, (-1/2) x (-3/4) = 3/8.

Front

How do you add fractions with the same denominator?

Back

To add fractions with the same denominator, add the numerators and keep the denominator the same. For example, (a/c) + (b/c) = (a+b)/c.

Front

What is the process for subtracting fractions?

Back

To subtract fractions, find a common denominator, adjust the numerators accordingly, and then subtract the numerators. For example, (a/b) - (c/b) = (a-c)/b.

Front

What is the reciprocal of a fraction?

Back

The reciprocal of a fraction is obtained by flipping the numerator and denominator. For example, the reciprocal of 3/4 is 4/3.

Front

How do you divide fractions?

Back

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

Front

What is a mixed number?

Back

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