Glenda wrote 2/10 of her paper on Monday, 1/10 of her paper on Tuesday, and 1/10 of her paper on Wednesday. She said she wrote more than half of her paper. Is she correct? Why or why not?
To find out how much she has written, we must add together all the work time. 2/10 + 1/10 + 1/10 = 4/10 which is less than 5/10 which would be half of the paper. So Glenda is wrong. She has only wirtten 4/10 of her paper.
