A grading machine can grade 96 multiple choice tests in 2 minutes. Suppose a teacher has 300 multiple choice tests to grade.



Write a proportion that could be used to predict the number of minutes it will take the machine to grade the
300
tests. Use x to represent the number of minutes.

The machine will take 6.25 minutes to grade 300 multiple choice tests.

Unitary method is a concept in which the value of a single unit is first found out and then multiplied by the necessary value to get the required answer.

Here, we are given that a grading machine can grade 96 multiple choice tests in 2 minutes.

This means that the machine will take 2/96 minutes to grade one multiple choice test

X = number of minutes taken by the machine to grade 300 multiple choice tests

Thus, we can use the proportion 2/96 to predict X in the following manner-

X = 2/96 (300)

X = 600/ 96

X = 100/ 16

X = 6.25

Thus, the machine will take 6.25 minutes to grade 300 multiple choice tests.
