Question

80 students took an algebra exam and 75 past it in simplest form what fraction of students did not pass the exam

Answer 1

1/16

Explanation:

That's a pretty good class average. Only 5 people didn't pass the exam, which we can get by subtracting 75 from 80.

Now, we can write it as a fraction. This is how well represent it in its simplest form.

If 5 out of 80 passed the exam, we could write it as 5/80. To simplify it as much as we can, We would want to turn 5 into 1, if thats possible for the other number without it turning into a decimal.

To turn 5 into 1, we can divide 5 by 5. Since we divided the numerator by 5, we have to divide the denominator by 5.

80/5=16

Put our answers as a fraction.

The simplest form is 1/16

Hope this helps!

Answer 2

1/16

Explanation:

75 of the 80 pass

80-75 = 5

That means 5 did not pass

Fraction that did not pass = people that did not pass/ total

= 5/80

divide the top and bottom by 5

=1/ 16
