Answer:
171 pounds
Step-by-step explanation:
So lets break this down
If the ratio between Ann and Bill is 2 : 9, then Bill gets 4.5 times more than Ann, because 9/2 = 4.5
We already know that Chloe and Dave get 2.5 times more than Ann
So let's first solve for how many pounds Ann gets, by this equation:
[tex]399 = 4.5x+2.5x+2.5x+x[/tex]
Where x is the amount that Ann gets
So lets solve:
[tex]399 = 4.5x+2.5x+2.5x+x\\399 = 10.5x\\x = 38[/tex]
So now we know that Ann gets 38 pounds, and Bill gets 4.5 times more than Ann, we we need to multiply 38 times 4.5., which equals 171 pounds
