# Thread: Please confirm these for me part 2

1. ## Please confirm these for me part 2

If a pair of shoes is now worth $180 because they were reduced by 20% The original price is$225 ?

2. You do not quite have the spirit of the task.

You must prove it, not guess at it.

How do you arrive at 225?
Wy do you doubt?

3. As \$180 is 80% of the original price, it's represented by this;

$0.8x = 180$

Hence,

$\frac{180}{0.8} = x = 225$

All in dollars, of course.

4. I guess we'll just never know if the student has a clue. Alas...

My apologies, I didn't see your post before I had already posted =/

6. I have workings but they are hand written

I was just checking if the answer was right or not, then I could post the workings if I had to

But you still did the work for him? It is better even then to give hints and lead them to their own conclusions. Thus they learn.

I didn't do it for him, since he'd already got the correct answer, I just explained my reasoning. If he'd got it wrong, I wouldn't have done so much. And at any rate, it's unfair to assume all people learn that way. For instance, I would learn it better simply by looking at what I posted, observing the method applied, and applying it to all future calculations of the same type. Thus, I learn. *Shrugs* To each their own I guess.

In future, please post your workings when asking for an answer to be checked. Thankyou.
