in plain and short, what is 60 on a ratio of 3:2.
well, the cheap way to do it is to just divide 60 by (3+2) and distribute accordingly, let's do that.
[tex] \bf \cfrac{blue}{orange}\qquad 3:2\qquad \cfrac{3}{2}\qquad \qquad \cfrac{3\cdot \frac{60}{3+2}}{2\cdot \frac{60}{3+2}}\implies \cfrac{3\cdot 12}{2\cdot 12}\implies \cfrac{36}{24} [/tex]
