Question

Are the ratios 25/45 and 15/27 proportional? Explain. Please help

Answer 1

Yes

Explanation:

because when we smaller them like 25/45 divide by 5 and 15/27 divide by 3 it forms 5/9

Answer 2

Yes. Easiest way too find it is plug them into your calculator, both solutions are .55555556. But if you don't have a calculator you can try to make the bottom numbers the same by seeing what they have in common...9. So 45/5=9 and 27/3=9. Then do the same to the top 25/5=5 and 15/3=5. Now we have 5/9 and 5/9 which are the same so they have the same proportions
