Answer:
The ratio would be 14 to 3.
Step-by-step explanation:
I like to think of ratios as fractions.
Since it is asking the ratio of yellow triangles to blue triangles, you would set 56 over 12 as a fraction.
(56)/(12)
56/12 can then be simplified to 14/3 because both 56 and 12 can be divided by 4
56/4 = 14
12/4 = 3
Your answer would then be a ratio of 14 to 3.
I hope this explanation helped and have a great day!
