• if I'm allowed to answer its b if not then ill delete this right away
• i hate math. I know that's bad but is it ok even though i work?
• You shouldn't hate math because you think it is hard. Everything is hard when you are learning it. Think about other things you have learned to do that took some time. Believe it or not, math is actually quite easy. If you have the mindset that you are never going to finish something, you never will. You shoulkd stay positive. It's okay to not be perfect at some things, but that doesn't mean that you should give up because it's hard. I like to challenge myself to do things I think is hard. And if we praise students for speed or making things look easy, then the message we are sending them is: I’m only smart when I’m fast or when something is easy. A lot of students say they don’t like math because they are struggling. But you need math to live the rest of your life. If you need help, just ask. That's what Khan Academy was made for.
• How is c not the answer, 2/3 is o.6?
• 2/3 does not equal 0.6
0.6 = 6/10 = 3/5 once reduced.
If you convert 2/3 to a decimal, you will get 0.66666... It is a repeating decimal. You can't truncate the number if you need to maintain the fractions whole value.

Hope this helps.
• once i watch the videos and then i go to a lesson i cant do it can someone help me😅
• I would watch the videos again and more carefully this time. Focus on equations and key words that Mr. Khan says.
• This is really easy to understand. Thank you!
• is there an easy way to do these?
• Yes use your brain 😉.

• Why doesn't it say that I've finished this? Watched it three times!!
• Did you fast forward the video at all? Sometimes it doesn't count the video if you fast-forwarded it.
• Why is the constant of proportionality represented as variable “k”. Can it be some other letter? Please help.
