can somebody like tell me the answer

Answer:
Mason is incorrect.
Step-by-step explanation:
Equivalent ratios are formed when the same number is MULTIPLIED to each number in the ratior, not when the same number is added. So for example, a ratio equivalent to 2:3 would be 4:6, because 2*2=4 and 3*2=6. You multiply to create equivalent ratios, not add.
(That would be your explanation)
