Answer 2

Step-by-step explanation:

Given : A pattern has 4 blue triangles to every 12 yellow triangles.

To find : What is the ratio of blue ?

Solution :

A pattern has 4 blue triangles and 12 yellow triangles.

Total number of triangles 4+12=16

The ratio of blue is

$r \: = \frac{number \: of \: blue \: triangles \: }{total \: number \: of \: triangles \: }$

$r = \frac{4}{16}$

$r \: = \frac{1}{4}$

Hence , a pattern has 4 blue triangles and 12 yellow triangles. Therefore, the ratio of blue is 1 : 4.
