Prove that 3: 8 is equivalent to 12: 32.
a. use diagrams to support your answer.
b. use the description of equivalent ratios to support your answer.

with Step-by-step explanation:

We are given that two ratios are 3:8 and 12:32

We have to find the given two ratios are equivalent

When two ratios a:b and c:d are equivalent then there exist x such that

c=ax and d=bx

Therefore, there exist 4 such that 12=4 times 3 and 32=4 times 8

Hence, the two ratios are equivalent.

Hence, proved.

correct answer:

b.(19,-2)
