How do you divide fractions?

To divide fractions, multiply by the reciprocal of the second fraction. For example, $$\frac{2}{3} \div \frac{4}{5} = \frac{2}{3} \times \frac{5}{4} = \frac{10}{12} = \frac{5}{6}$$ after simplification.

What is a mixed number?

A mixed number is a whole number combined with a fraction. For example, 1 1/2 is a mixed number, which can also be expressed as $$\frac{3}{2}$$ .

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

To convert an improper fraction to a mixed number, divide the numerator by the denominator. The quotient is the whole number, and the remainder over the original denominator is the fraction. For example, $$\frac{7}{4} = 1 \frac{3}{4}$$ .

What is the least common multiple (LCM)?

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.
