A fraction represents a part of a whole and is written as $$\frac{a}{b}$$ , where 'a' is the numerator and 'b' is the denominator.

What is a proper fraction?

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

What is an improper fraction?

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

How do you find a common denominator for $$\frac{1}{3}$$ and $$\frac{1}{4}$$ ?

The common denominator for $$\frac{1}{3}$$ and $$\frac{1}{4}$$ is 12, as it is the least common multiple of 3 and 4.

What is the process to add $$\frac{9}{10}$$ and $$\frac{3}{4}$$ ?

Convert $$\frac{3}{4}$$ to $$\frac{15}{20}$$ , then add: $$\frac{9}{10} = \frac{18}{20}$$ , so $$\frac{18}{20} + \frac{15}{20} = \frac{33}{20} = 1\frac{13}{20}$$ .

What is the result of $$\frac{3}{4} - \frac{1}{5}$$ ?

Convert to a common denominator (20): $$\frac{15}{20} - \frac{4}{20} = \frac{11}{20}$$ .

How do you find an equivalent fraction for $$\frac{18}{24}$$ ?

Divide both the numerator and denominator by their GCF, which is 6: $$\frac{18 \div 6}{24 \div 6} = \frac{3}{4}$$ .

What is the result of $$4\frac{1}{4} - 2\frac{3}{8}$$ ?

Convert to improper fractions: $$\frac{17}{4} - \frac{19}{8}$$ . Find a common denominator (8): $$\frac{34}{8} - \frac{19}{8} = \frac{15}{8} = 1\frac{7}{8}$$ .

What is the greatest common factor (GCF)?

The greatest common factor is the largest number that divides two or more numbers without leaving a remainder. For example, the GCF of 8 and 12 is 4.
