Question 49768: I am actually baffled, I am asking this for my daughter, I cannot help her because my math is very limited so even if I read how to solve I would not get very far. It is a story problem involving geometry (I think). Here is her story problem question:
To promote a new delivery service, Pizzaroo is including a free Collectable Card with every pizza purchase. What a deal! So you decided to order a Jelly Bean Pizza. Yum!
When the pizza arrived, you noticed that the free Collectable Card was in the corner of the square box, so that its corner just barely touched the outside of the perfectly-circular pizza. The Collectable Card measures exactly 140 mm by 70 mm.
What is the diameter of the pizza, in millimetres? Please round to the nearest millimetre.
Thanks for your help in advance!

Question 51177: Hello, I have a problem that has been answered here already. The problem is, I don't quite understand how he arrived at the answer. The problem and answer is here: http://www.algebra.com/cgi-bin/jump-to-question.mpl?question=19628
The original question is: Suppose that the length of a rectangle is one and one-third times as long as its width. The area of the rectangle is 48 square centimeters. Find the length and width of the rectangle.
The answer given is:
LET WIDTH =W
LENGTH=one and one-third times as long as its width.=(1 and 1/3)(W)..=(4/3)(W).
=4W/3
SO AREA =L*W=(4W/3)*W=48
W*W=48*3/4=36
W=6 CM
L=4W/3=4*6/3=8 CM
I understand most of it, until the line w*w=48*3/4=36 , I'm not sure I understand how he turned 4/3 into 3/4 and multiplied it by 48. I thought one could only add or subtract when bringing a fraction across? Sorry if this is a dumb question.
