#1 Re: Help Me ! » simple ratio problem too much for me! » 2009-01-21 14:47:44
Is there a reference on here to explain scale ratios to someone who doesn't understand the first thing about it? How do you know when to put the number (ie: Height of roller coaster is 80m. Diagram height is 10 cm. What is the scale ratio?)
I am SO lost!! Is there a sure way method to know which number goes on the bottom (ie: 1/80 or the top, ie: 80/1)... I have no clue about this and I'm desperately trying to help my son, who is grade 8.
Please help!
