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. For example, to add 1/4 and 1/3, the common denominator is 12: (1/4 = 3/12) + (1/3 = 4/12) = 7/12.

What is the process to subtract fractions?

Back

To subtract fractions, ensure they have the same denominator. If not, find a common denominator, convert the fractions, and then subtract the numerators. For example, 3/4 - 1/2 = 3/4 - 2/4 = 1/4.

Front

What does it mean to multiply fractions?

Back

To multiply fractions, multiply the numerators together and the denominators together. For example, (1/2) * (3/4) = (1*3)/(2*4) = 3/8.

Front

How do you divide fractions?

Back

To divide fractions, multiply by the reciprocal of the second fraction. For example, (1/2) ÷ (3/4) = (1/2) * (4/3) = 4/6 = 2/3.

Front

What is the least common multiple (LCM)?

Back

The least common multiple (LCM) of two or more numbers is the smallest number that is a multiple of each of the numbers. For example, the LCM of 4 and 5 is 20.

Front

What is the greatest common divisor (GCD)?

Back

The greatest common divisor (GCD) of two or more numbers is the largest number that divides each of the numbers without leaving a remainder. For example, the GCD of 8 and 12 is 4.

Front

How do you simplify a fraction?

Back

To simplify a fraction, divide the numerator and the denominator by their greatest common divisor (GCD). For example, to simplify 8/12, divide both by 4 to get 2/3.
