Astudy at a major university concluded that many students are cheating

Right 1500

We know that 675 of the students surveyed said they cheated in 1 to 7 courses, and this represents 45% of the total students that participated in the survey, as shown in the graph.

If we want to know the total students surveyed (100%) we can use the Rule of Three as follows:

if 45% represents -----675 students

100% represents--------X students

or

45% -----675 students

100% --------X students

And this is solved in the following way:

Finally:

X=1500>>>>>This is the total amount of students surveyed or the 100%

step-by-step explanation:

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
