Question

Glenda wrote 1/7 of her paper on Monday, 1/14 or her paper on Tuesday, and 2/28 of her paper on Wednesday. She said she wrote more than half of her paper. Is she correct? Why or why not?

Answer 1

Well to figure this problem out, first we need to figure out a common denominator for all these amounts, so what do you think would be the common denominator for 7 14 and 28

Answer 2

No, Glenda only wrote 2/7 of her paper.
Take 1/14 and divide by 2 on both the numerator and denominator to get 0.5/7.
Take 2/28 and divide by 3 on both the numerator and denominator to get 0.5/7.
This allows the fractions to all have the same denominator and they are now able to be added.
Once added, you will get 2/7.
