6. A proportion is an equation showing two equal ratios. Give an example

Take any fraction, proper or improper, and then multiply both the numerator and denominator by any number you want.

An example is one-half (1/2)

1/2 = 2/4 = 4/8 = 12/24 = 25/50 = 50/100 = 1000/2000 = 1024/2048

All of those are the same 1:2 ratio, just expressed in different forms.
