Question

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?

Answer 1

She's wrong because she's only written half and she's stating that se's written MORE THAN half

Answer 2

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.
