Answer 1

Answer:

I think c one is the correct answer

Answer 2

Answer:

1. is in proportion

2. is in proportion

3. is in proportion

Step-by-step explanation:

we know

product of extremes if equal to product of means then the given set is in proportion

hence,

1.25×48=1200

30×40=1200

hence they are equal and thus in proportion

2. 33×100=3300

44×75=3300

hence,they are equal

3. 30×24=720

45×16=720

hence they are equal.
