Ответ:
The number of students per year increasing
Ответ:
40
Step-by-step explanation:
From both of the fractions the denominators are 8 and 10. For all of the multiples of 10, the unit digit contains a 0. But multiples for the number 8 can vary from different varaties of numbers. After realizing this information, I can assume the largest possible lcd for these fractions is 80. But we can double check if their is an lcd which is less then 80. Numbers 10,20,30 can't work because they aren't a multiple for 8. But the number 40 can work because its multiple for the number 8 and 10.
