Homework Help: Fraction help wrong answer

Posted by Matty on Thursday, January 10, 2013 at 8:41pm.

It takes Nadia 4/9 h to complete her Language Arts homework and 2/9 h to complete her mathematics homework. Which takes longer? How much longer?

I did this :

It takes Nadia Language Arts home work longer by 13.34 minutes longer.
4/9 x 60 min = 240/9 = 26.67 min
2/9 x 60 = 120/9 = 13.33 min

26.67 - 13.33 = 13.34 min

I got this wrong? I was suppose to keep it in fractions. And I came up with it took Languarge Arts longer ? Do I just turn the 26.67 and 13.33 into a fraction? then subtract the two minutes? Please help.

You are right. The language arts homework takes longer than the math homework. The language arts homework takes 2/9 of an hour longer.

13.33 min is correct if rounded to the nearest 0.01 minute. As a fraction, that would be 2/9 hour, 120/9 hour or 13 1/3 min.

Thank you both. I understand the fraction part now that I didn't understand.

You should ask your teacher for help instead of cheating on the internet.
