Answer: OPTIONS C, D and E.
Step-by-step explanation:
First, it is important to remember the definiton of "Ratio".
A ratio is defined as a comparison between two number numbers "a" and "b" (
).
By definition, a ratio can be expressed in the following forms:
1. In words. This is:
![a\ to\ b](https://tex.z-dn.net/?f=a%5C%20to%5C%20b)
2. In odds notation, as following:
![a:b](https://tex.z-dn.net/?f=a%3Ab)
3. In fractional notation. This is:
![\frac{a}{b}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bb%7D)
In this case you know that there are 5 green tiles for every 3 blue tiles in a mosaic.
Then, based on the explained before, the ways you can write the ratio of blue tiles to green tiles, are:
![\frac{3}{5}\\\\3:5\\\\3\ to\ 5](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7D%5C%5C%5C%5C3%3A5%5C%5C%5C%5C3%5C%20to%5C%205)
