This is my blog post for my homework, question number 25.

25) Create a word problem that involves operations with rational numbers in decimal form. Make sure you can solve your problem. Then, have a classmate solve your problem.

A) Casey likes basketball. So he's on a basketball team. Casey goes to practice every Monday and Friday. He practices on Monday for 1.8 hours. On Friday he practices for 120 min. What is the difference between Monday and Friday's practices in minute form.

Solution) First you would convert Monday's hours into minutes. = 140 min.

Secondly you would then just subtract Friday's hours from Mondays, because Friday is already in minute from.

140 - 120 = 20 min.

20 min is the difference.

Please comment on my mistakes ! Thank you !

Check your math,Frank

Okay 1.8 hours is 1 hour and 8/10 of an hour. Since 1/10 of an hour is 6 minutes, then 8/10 must be 8 x 6 minutes = 48 minutes. Total is 60 minutes + 48 minutes = 108 minutes. Anyone for metric time? ;-)

haha.niice franky!!had to use mee? good job though!

Good job frank! but how do you know that the .8 of 1.8 is 140 minutes?
