9a: 1/5. She takes a 1/5 and puts it in each so your fraction is 1/5

9b: $105. 525 / 5 = 105

10: Option 1. He gains more money this way.

In option 1 if he gets his allowence for 4 weeks, he would make $15 (1+2+4+8).

But in option 2 he would only make $4 because the square of 1 is 1 (1+1+1+1)

Hope that helps and hope I did that correctly

Total amount = $525

Split by a fraction, divide by 5 and then again divide by 5:

  • 525*1/5*1/5 = 525*1/25 = 21
  • a) The fraction = 1/25
  • b) The amount = $21

#10

Option 1 results in sequence:

  • 1, 1*2=2, 2*2=4, 4*2=8, etc

Option 2 results in sequence:

  • 1, 1² = 1, 1² = 1, 1² = 1, etc.

It's obvious that option 1 is a better choice.
