Ann is growing two different plants for a science project. plant a grew 4/12 inch the first week and 2/12 inch the second week. plant b grew 8/12 inch of the first week and did not grow after that. which plant is taller now?

oh wait
do u need a number line
well .. ok

Start the number line from 0 and put divisions at 1/12. Then mark at 4/12 for plant A and indicate this was its growth in the first week. Then, make another mark up to 6/12 and indicate this was the plant's growth in the second week.
For plant B, make one mark at 7/12 and indicate that this is plant B's growth in the first week.

After two weeks, plant A has a height of 6/12 inches and plant B has a height of 7/12 inches, so B is taller.
