(80)/(15)
Reduce the expression (80)/(15) by removing a factor of 5 from the numerator and denominator.
(16)/(3)
The approximate value of (80)/(15) is 5.33.
5.33 nuber of students who bought

Since 80 goes into 1600 20 times,
multiply 20 times 5.33
20*5.33
Multiply 20 by 5.33 to get 106.6.
106.6
Rounded up, about 107 students would buy the product.
