Question

the ratio of yellow tulip bulbs to red tulip bulbs in a package is 2 to 3. There are 100 tulip bulbs in the package. H ow many of each color bulb is there?

Answer 1

we know the ratio of yellow and red tulips are 2 : 3, if there are 100 total, let's simply divide 100 by (2 + 3) and distribute accordingly.

`\stackrel{\textit{\large yellow to red tulips ratio}}{\cfrac{\stackrel{\textit{yellow tulips}}{y}}{\stackrel{\textit{red tulips}}{r}} = \cfrac{2}{3}}\qquad \qquad \cfrac{2\cdot (100)/(2+3)}{3\cdot (100)/(2+3)}\implies \cfrac{2(20)}{3(20)}\implies \cfrac{\stackrel{yellow}{40}}{\underset{red}{60}}`
