A fraction represents a part of a whole. It consists of a numerator (top number) and a denominator (bottom number). For example, in the fraction $$\frac{3}{4}$$ , 3 is the numerator and 4 is the denominator.

Convert $$\frac{1}{4}$$ to a fraction with a denominator of 16.

To convert $$\frac{1}{4}$$ to a fraction with a denominator of 16, multiply both the numerator and denominator by 4: $$\frac{1 \times 4}{4 \times 4} = \frac{4}{16}$$ .

What is the sum of $$\frac{7}{16} + \frac{1}{4}$$ ?

First, convert $$\frac{1}{4}$$ to $$\frac{4}{16}$$ . Then, add: $$\frac{7}{16} + \frac{4}{16} = \frac{11}{16}$$ .

What is the process to find the sum of $$\frac{1}{12} + \frac{5}{8}$$ ?

First, find the least common denominator (LCD), which is 24. Convert the fractions: $$\frac{1}{12} = \frac{2}{24}$$ and $$\frac{5}{8} = \frac{15}{24}$$ . Then, add: $$\frac{2}{24} + \frac{15}{24} = \frac{17}{24}$$ .

What is the sum of $$\frac{1}{3} + \frac{2}{5}$$ ?

First, find the LCD, which is 15. Convert the fractions: $$\frac{1}{3} = \frac{5}{15}$$ and $$\frac{2}{5} = \frac{6}{15}$$ . Then, add: $$\frac{5}{15} + \frac{6}{15} = \frac{11}{15}$$ .

How do you add $$\frac{1}{2} + \frac{3}{8}$$ ?

Find the LCD, which is 8. Convert $$\frac{1}{2}$$ to $$\frac{4}{8}$$ . Then, add: $$\frac{4}{8} + \frac{3}{8} = \frac{7}{8}$$ .

What is a mixed number?

A mixed number is a whole number combined with a fraction. For example, $$2 \frac{1}{2}$$ is a mixed number.

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 is the new numerator.

What is the sum of $$\frac{1}{2} + \frac{3}{8} + \frac{1}{4}$$ ?

Convert all fractions to have a common denominator of 8: $$\frac{1}{2} = \frac{4}{8}$$ and $$\frac{1}{4} = \frac{2}{8}$$ . Then, add: $$\frac{4}{8} + \frac{3}{8} + \frac{2}{8} = \frac{9}{8} = 1 \frac{1}{8}$$ .

What is the importance of simplifying fractions?

Simplifying fractions makes them easier to understand and work with. It helps to express the fraction in its simplest form.
