What is Cameron's error??????
pogonyaev

Answer

Cameron forgot to do the same thing to the 9. Instead of dividing 3 by 3 and 9 by 3 he only divided 3 by 3.

Step-by-step explanation:

3/7 × 4/9

You can divide the 3 and 9 by 3 so you get 1/7 × 4/3.

Then you do 4 × 1 and 7 × 3.

Correct answer is 4/21

Answer:

The coordinates of J are missing.  Plus, I don't see options for the conclusions.  I made an imaginary point J, which you could correct to form the proper triangle.

Step-by-step explanation:

See the attachment.  Plot all the vertices, including a corrected point J and draw the resulting triangle.  It might be that AJKL is a slightly smaller, shifted version of AGHI.  Enter the correct coordinates and then compare.

How to answer the question
bulgar [2K]

That is sudoku, a game that I am really good at. first off the square on the left in the middle is messed up, because on the square above it there is a 5 where it would make the 5 in the middle left square incorrect. So you have to erase the 5 in the square on the middle left. Then if you can do sudoku, you could do the rest.

hope I helped!
