Question 723748: This is a simple math problem, I apologize. But I am having trouble finishing 3 digit by 3 digit multiplication problems, for example:
538*342. I, like most folks start with 538 *2. 8*2 is 16 carry the one over to the tens place. 3*2 is 6 plus the 1 is 7. 5*2 is 10. So 538*2 is 1076. 538 *4. 4*8 is 32 carry the 3 and put it above the tens place. 3*4 is 12 plus 3 is 15.put the 1 above the 5. 5*4 is 20 + 1 is 21. 538*4 is 2152. I get lost when it come to the hundreds place in 538*342. What do I do with the 3 in the hundreds place?

Question 724109: I'm taking algebra and our final project is about how math is related to a Graphic Designer. My scenario is creating a logo. And my logo got chosen. It must now be enlarged for a billboard. Typical billboards are 14 by 48 feet; 12 by 24 feet; and 5 by 11 feet. The largest sign is the one you most often notice along the freeway.
What will the new scale factor need to be? (Hint: Your original design and enlargement were measured in centimeters. Billboards are measured in feet. 1 inch = 2.52 centimeters.)
I haven't made up any dimensions yet. I don't know what a typical logo design size is. Maybe 10cm by 20cm?
How should I solve this? Please help!
