Final answer:
To find the number of research reports that Tarik will complete during the school year, set up a proportion using the given information and solve for the unknown number of reports.
Step-by-step explanation:
To find the number of research reports that Tarik will complete during the school year, we need to know the total number of reports for the year. Since the teacher says that 20% of the reports are done, we can set up a proportion to solve for the unknown number of reports.
Let's assume that the total number of reports for the year is 'x'. Then, we can set up the proportion:
20% of x = number of reports done
To solve for 'x', we can convert 20% to a decimal by dividing it by 100: 20/100 = 0.2
So, the equation becomes: 0.2x = number of reports done
To solve for 'x', we can divide both sides of the equation by 0.2: x = number of reports done / 0.2
Therefore, Tarik will complete x number of research reports during the school year.
