Fractions is one of the very basic and important representation in mathematics. A fraction is a number that can be expressed in p/q form. This representation can also be understood as division of two numbers or quantities as the top is the numerator and the bottom is the denominator. The denominator of a fraction can never be equal to zero. Fractions can be further simplified according to the requirement. Different mathematical operations can be used to simplify and solve a given fraction.

Example 1: Amy brought 20 pencils. She uses all the pencils in 5 weeks equally. How many pencils per week did she use?
Solution: Number of pencils brought by Amy = 20.
Number of weeks she took to finish the pencils = 5.
Number of pencils per week = 20/5.
The GCF of 20 and 5 is 5. Dividing the numerator and the denominator by 5.
This gives 20 ÷ 5 /5 ÷ 5 = 4.
Hence, Amy used 4 pencils per week.
