Please help me!!! Its math and I am struggling

Romashka-Z-Leto [24]

Answer:

16:36 = 32:72 = 12:27

Step-by-step explanation:

An easy way for me to solve this is to divide the first value by the second. If they turn out to be the same fraction, then they are equivalent.

Is 16:36 = 32:72?

Yes, because $\frac{16}{36}=\frac{4}{9} =\frac{32}{72}$

Is 16:36 = 12:27?

Yes, because $\frac{16}{36}=\frac{4}{9} =\frac{12}{27}$

Is 16:36 = 3:4?

No because $\frac{16}{36}=\frac{4}{9} \neq \frac{3}{4}$

I hope this helps!!! Please rank if it does and let me know if you have any more questions about this!
