Question

A pattern has 15 blue triangles to every 20 yellow triangles. What is the ratio of yellow triangles to all triangles?

Answer 1

Answer is   4:7

Explanation:

There are 20 yellow triangles and 15+20 = 35 triangles total.

The ratio of yellow to total is 20:35. The order is important.

Answer 2

Answer:

There are 35 total triangles, so the ratio of yellow to all triangles is 20 / 35
