Respuesta :

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

Answer:

Ratio's are equivalent

Step-by-step explanation:

we have to determine if each pair of ratios or rates is equivalent:

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
