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?

Answer 1

( 1 / 7 ) * 4 / 4 = 4 / 28

( 1 / 14 ) * 2 / 2 = 2 / 28

1 / 7 + 1 / 14 + 2 / 28 =

4 / 28 + 2 / 28 + 2 / 28 =

8 / 28 =

4 * 2 / ( 4 * 7 ) =

2 / 7 = 0. 2857 = 28.57 %

She wrote less than half of her paper becouse :

1 / 2 = 50 %
