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

To convert a mixed number to an improper fraction, multiply the whole number by the denominator and add the numerator. For example, $$2 \frac{1}{2} = \frac{2 \times 2 + 1}{2} = \frac{5}{2}$$ .

What is the least common denominator (LCD)?

The least common denominator (LCD) is the smallest number that can be used as a common denominator for two or more fractions. For example, the LCD of $$\frac{1}{4}$$ and $$\frac{1}{6}$$ is 12.

How do you add fractions with different denominators?

To add fractions with different denominators, first find the least common denominator (LCD), convert the fractions to equivalent fractions with the LCD, and then add the numerators. For example, $$\frac{1}{4} + \frac{1}{6} = \frac{3}{12} + \frac{2}{12} = \frac{5}{12}$$ .

What is a reciprocal?

A reciprocal of a fraction is obtained by flipping the numerator and denominator. For example, the reciprocal of $$\frac{3}{4}$$ is $$\frac{4}{3}$$ .

How do you divide fractions?

To divide fractions, multiply the first fraction by the reciprocal of the second fraction. For example, $$\frac{1}{2} \text{ ÷ } \frac{3}{4} = \frac{1}{2} \times \frac{4}{3} = \frac{4}{6}$$ , which simplifies to $$\frac{2}{3}$$ .

What is a proper fraction?

A proper fraction is a fraction where the numerator is less than the denominator. For example, $$\frac{3}{4}$$ is a proper fraction.

What is an improper fraction?

An improper fraction is a fraction where the numerator is greater than or equal to the denominator. For example, $$\frac{5}{4}$$ is an improper fraction.

How do you find the total amount needed when given a fraction of a total?

To find the total amount needed when given a fraction, divide the known amount by the fraction. For example, if $$\frac{1}{3}$$ of the total is 3 pounds, then the total is $$3 \text{ ÷ } \frac{1}{3} = 9 \text{ pounds}$$ .
