Answer:
subtract the number you have from the number you're going to. For example, if you were trying to figure out the distance between 6 and 18, you would subtract 6 from 18 which is 12. I hope this answers your question!
Step-by-step explanation:
a = 6, b = 22.5
One triangle is 2.5 times bigger than the other.
9*2.5=22.5 which means b = 22.5
15/2.5=6 which means a = 6
