Answer 1

yes they're equivalent, 15x3=45 and 45x3=135 therefore they are both multiplied by three and are equivalent

Answer 2

Ratio's are equivalent

Explanation:

15 computers for 45 students

Ratio of computers to students= 15:45

= 1:3

45 computers for 135 students

Ratio of computers to students= 45:135

= 1:3

Hence, The ratio's are equivalent
