Question 632627
First of all, let's isolate the important information. The first sentence is irrelevant to the problem, so don't let that number get into your head.
<p>What we do know is that he ended up with 1 orange at the end of this transaction, and he gave half and half of that half. All in all, the original amount of oranges he had got divided by <b>1/4</b>, because 1/2 x 1/2 is equal to 1/4. When we reverse 1/4, we get 4. To find out how many oranges Peter started it, we must multiply the number of oranges he has now by 4. We know he has 1 orange now, so {{{1*4=4}}}
<p><b>Peter originally had 4 oranges.</b>
<p>Hope this helps! :)
