Word problems are the problems in math which are expressed in words and the required data should be taken from the questions and further be solved. Fractions are numbers that can be expressed in the p/q form. Here p the numerator and q is the denominator of the fraction. Different mathematical operations can be used to solve such questions such as addition, subtraction, multiplication and division. Fractions are very common and are regularly used in different branches of mathematics.
Example 1: There are 15 cookies in the cookie jar. If a group of children eat one-third of the cookie jar, how many cookies are remaining in the jar?
Solution: Total number of cookies in the cookie jar = 15.
Fraction of the cookie jar eaten by the children = 1/3.
Amount of milk = Fraction of milk * number
Therefore, amount of cookies reining in the cookie jar = 15 x 1/3 = 15/3 = 5
Hence, number of cookies remaining in the cookie jar = 5.
Question: Multiple choice question (Pick the correct option.)
There are 20 students in a classroom. If two fifth of the students are absent on a snowy day, how many number of students are absent on that day?
a) 12 b) 5 c) 8 d) None of these.
Correct answer: option c.
Explanation: Number of students in a classroom = 20.
Fraction of the student absent = 2/5.
Therefore the number of students absent = 20 x 2/5 = 40/5 = 8.
