Answer:
86.5 green buttons
Step-by-step explanation:
In a jar, there are pink, blue, green buttons.
They are divided in ratio forms:
Make the ratio unit for the blue same, so that we can relate both together.
- pink : blue = (2 : 7) * 3 ⇒ (6, 21)
- blue : green = (3 : 4) * 7 ⇒ (21, 28)
All together :
- pink : blue : green = 6 : 21 : 28
Let each button be "x"
simplify
divide both sides by 55
So greatest green button:
- 86.5 green buttons (rounded to nearest tenth)
