Fractions word problems with graphs and tables :
Here we are going to have information in the form of graph and table.
From the table, we have to understand the information and answer the given question.
Let us look into some example problems to understand the concept.
Example 1 :
John's family expenses are 7000 dollars a month. He made a pie chart on their expenses for food, housing, saving, clothing, entertainment and music.
From the given information find,
(i) How much money does he spend for clothing and entertainment.
He spends 11% for clothing and 13% for entertainment. The sum of these two expenses are 11 + 13 = 24%
To find the exact amount, we need to calculate 24% of his salary.
His salary = 7000 dollars
= 24% of 7000
= (24/100) x 7000
Hence he spends $1680 for clothing and entertainment.
Example 2 :
Nanyung university offers four applied majors and monitors the number of students in each.
What fraction of the students in applied majors are majoring in computer science?
Number of students applied in computer science = 190
Total number of students = 210 + 360 + 190 + 100
To find fraction divide 190 by 860,
Example 3 :
The graph below shows the information on the number of farm animals owned by Betty.
(i) What is the total percentage of animal owned by Jason and Walter ?
(ii) How many animals are owned by Daniel
Percentage of animals owned by Jason = 30%
Percentage of animals owned by Walter = 120%
Total percentage = (30/100) + (120/100)
= (30 + 120)/100
Hence 150% of animals owned by Jason and Walter.
Percentage of animals owned by Daniel = 50%
From this we have to understand that, Daniel is having 50% of animals in total number of animals
Total number of animals = 120 + 90 + 50 + 10 + 30
Total number of animals that Daniel has
= (50/100) x 300
