Can you help me with this question please

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:

Where x is the amount that Ann gets

So lets solve:

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
