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

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.

We divide both parts by the GCF 5 to get the reduced ratio 4:7

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

or 20 to 35 or 4 to 7

Step-by-step explanation:

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
