Answer:
- you - 4 rocks and 16 fossils
- friend - 12 rocks and 8 fossils
Step-by-step explanation:
Let the rock be r and the fossil be f
<u>Equations</u>
- You: r + f = 20
- Friend: 3r + 1/2f = 20
<u>Double the second equation and subtract the first one:</u>
- 2(3r + 1/2f) - (r - f) = 2*20 - 20
- 6r - r = 20
- 5r = 20
- r = 4
<u>Then find f:</u>
So you collect 4 rocks and 16 fossils
<u>Friend collects:</u>
- 4*3 = 12 rocks and
- 1/2*16 = 8 fossils
You would do 15 divided by 5 equals 3, and 5 divided by 5 equals 1, so it would turn into 3/1 times 3/18. Then,18 divided by 3 equals 6, and 3 divided by 3 equals 1, so the final answer would be 1/1 times 3/6, which equals 1/2 or 3/6.
