Begin with the ratio

0.5 : 0.75

Multiply both parts of the ratio by 2:

1 : 1.5

You can multiply by two again:

2 : 3

Both of these are simplified compared to the original. Which one is used depends on how the ratio is being used. Some ratios are easier to work with and understand with whole number so 2 : 3 would be used. In other cases, using 1 as part of the ratio makes it easier to work with, so then 1 : 1.5 may be used.

All of them describe the same ratio.
