Ok let's see.
The way to tackle this, is to first add up the ratio's.
So 4+8 = 12. Now this 12 is important as this is total number of shares (bunches) we need to allocate to 2 different flower colours.
Before we can know how much flowers = 4 and 8 bunches. We first need to work out how many flowers = 1 bunch.
It's simple.
108 (total number of flowers) ÷ 12 (bunches of flowers) = 9 flowers per bunch.
So if 1 bunch = 9 flowers.
4 : 8
= (4 bunches x 9 flowers) : (8 bunches x 9 flowers)
Which leads to...
36 purple : 72 black
