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" ([tex]b\neq 0[/tex]).
By definition, a ratio can be expressed in the following forms:
1. In words. This is:
[tex]a\ to\ b[/tex]
2. In odds notation, as following:
[tex]a:b[/tex]
3. In fractional notation. This is:
[tex]\frac{a}{b}[/tex]
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:
[tex]\frac{3}{5}\\\\3:5\\\\3\ to\ 5[/tex]
