Glenda wrote 1/7 of her paper on Monday, 1/14 of 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?

1/7 + 1/14 + 2/28 (I assume period is typo)

4/28 + 2/28 + 2/28 = 8/28 = 4/14 which is less than 7/14 which would be one half

Manuel wrote a 512-word paper over the weekend. He wrote 180 more words on Sunday than he did on Saturday. How many words did he write on Saturday?

To determine if Glenda is correct in saying she wrote more than half of her paper, we need to calculate the total percentage of the paper that she wrote.

First, let's calculate the percentage she wrote on Monday:
1/7 * 100% = 14.29%

Next, let's calculate the percentage she wrote on Tuesday:
1/14 * 100% = 7.14%

Lastly, let's calculate the percentage she wrote on Wednesday:
2.28 / 100% = 2.28%

Now, let's find the total percentage of the paper Glenda wrote by adding the percentages of each day:
14.29% + 7.14% + 2.28% = 23.71%

Since Glenda wrote only 23.71% of her paper, which is less than half (which would be 50%), she is not correct in saying she wrote more than half of her paper.
