Hi OK,

1. james ate one fifth of a pumpkin pie. Ryan ate 1/4 of the pie. How much of the pie is left?

2.a costume normally sells at $30 is on sale for 30% off. After the dedcution is taken, an additional 7% nust be paid for sales tax what is the total cost of the costume?

Plzz help me answer I'm so confused! Thanks :)

What have you got so far?

Have you figured out the equation?

Show us the work you've done and we'll lead you in the right direction.

For the first question with the pie, change the pie into whole numbers using the degrees in a circle which is 360. Using the 360 divide by 5 which equals 72. Subtract 72 from the 360 which is 288. Now take the 288 and divide it by 4 which is 72. Subtract the 72 from 288 to get 216. Now take 216 over 360 and convert that into a smaller fraction to get what is left of the pie. Let me know if this is to confusing.

For the second question take 30 and multiply it be .30 which is 9. Subtract 9 from 30 which is 21. Now take 21 and multiply it by .07 to for the sales tax which is 1.47. Now take the 21 and add 1.47 to get 22.47 which is the final cost of the costume. Let me now if this is confusing as well.

Hope this helps.

It's great that you gave the equations but please don't give the answers.

The rules of this site are not to do the homework for the people asking, but to help them find the answer for themselves.

It won't help them if we just give them the answer. We're here to help, not to do someone's homework.

Other then that, you did great. :)

This is why I asked to see the work that the OP had done, so I could see what he/she already did then steer them in the right direction. :)

Ok, not sure of all the rules yet, just started a couple of days ago and already really like this site, but I love math more. Hopefully it will help her understand anyway.

Like I said, you did great, you gave her the equation, all you had to do is leave out the answer, ask her to do it and then post it so you could help her along. :)

Welcome to the site.

As for loving math, well, I can't understand that. I hated math when I was young, I'm still not fond of it. ;)

I have a different idea not involving degrees. Hard to tell what level this is at, but I'm going to assume you're supposed to know how to do fractions?

If one person ate 1/5 of a pie and one person ate 1/4, how much total was eaten? You have to find a common denominator. Once you have that, take that away from the whole pie (1) and you know how much is left.

As a general rule, just seeing answers doesn't help most of the time. (There are exceptions.) Even seeing calculations doesn't necessarily help if they don't know where you got things from or why you're doing it. And having that "why" missing is what prevents people from understanding things. (It might get them a grade for their homework, but no more.)

Just for instance, if you don't explain why you're multiplying by .30, it doesn't mean anything if they don't know why you're supposed to do that.

Also, many times people actually have made an attempt at the work and even have it right, but they don't bother to post it. Or if it's not right, it's easier to see where they are going wrong if we see the work. They will also learn better by correcting mistakes than just being told what to do.

And lastly, it's also not really ethical to do people's work for them. Unfortunately, a lot of people are looking for just that: someone else to just give them answers, because other sites do it.
