Cal Posted March 5, 2007 Report Posted March 5, 2007 AGH! I have a Maths questions, I need help! It's on the subject of Arithmetics. 1. x:y:z = 2:4:5. If z=35, find x and y. 2. The scale on a map is 1:25000. The length of a wall on the map is 3.2mm. Find the actual length in metres. Any help would be much appreciated!
Jess Posted March 5, 2007 Report Posted March 5, 2007 Okay.... So, 1) is ratio. z = 35 and is in five parts. So, therefore, each part is 35/5 = 7. So to find x and y, you just multiply each of their respective ratios (2 and 4) by 5. Does that make sense to anyone but me? I'm rubbish at explaining things... I'm no good with map scales, sorry!
Cal Posted March 5, 2007 Report Posted March 5, 2007 Jess, you are a saint! Thanks so much! *Gives Jess M&S Hoisin Duck Pancakes* <- I know you like them!
Jess Posted March 5, 2007 Report Posted March 5, 2007 ^^ Oh, you remembered! Thanks! Glad that my GCSE Maths was of some use.
Cal Posted March 5, 2007 Report Posted March 5, 2007 Hehe! Now, on to do the Wuthering Heights essay............oh joy.

The scale on a map is 1:25000. The length of a wall on the map is 3.2mm. Find the actual length in metres. Any help would be much appreciated! Map question is just basically 3.2mm times 25000. But remember these measurements are in millimetres. Because the basis is that every 1mm on the map is equal to 25000mm in real life. So 3.2mm would equal to 25000 x 3.2mm in real life. Hope that helps. I just had a Maths test today, which may I mention was very stressful and barely anyone in the class finished it in time!! -sigh- Ramble over...
Marieh Posted March 6, 2007 Report Posted March 6, 2007 British cartoons, anyone? *feels stupid because she just thinks about american ones*
Jess Posted March 6, 2007 Report Posted March 6, 2007 Beano? Edit: As in television cartoons, or comic books?
