Netta drew a picture on graph paper:
[IMG]
She said,
In my picture, a big square represents 1. Since ten rectangles make a big square, a rectangle represents 0.1. Since 100 little squares make a big square, a little square represents 0.01. So this picture represents 2.43.
Is Netta Correct?
Manny said,
I drew the same picture, but in my picture, a little square represents 1, so this picture represents 243.
