[SOLVED] (51/36)x180=255 AND 1.25x180=255 ? help please

i was just working out some simple calculations and came across this anomaly . 51/36 (equalls 1.416666...) multiplied by 180=255. but 1.25 multiplied by 180 also equals 255 (note that its not 1.416666...and when multiplied by 180 it still equals 255) can someone exlpain this to someone of Inferior intelligence. how can 255=180x1.25 AND 180x51/36!

180*1.25=225

? *raises eyebrow* that doesn't answer my question...

(51/36)*180=255 AND 1.25*180=255. is that better?

(51/36)*180=255 AND 1.25*180=255. is that better?

Look a bit more carefully!

Do the calculation again.

brandy
eek. i don't understand. sure 1.25*180=255. but so does 51/36*180. what are you trying to get at? 51/36 does not equal 1.25.

Do the calculation again, and pay great attention to the numbers that come up on the screen. 1.25 x 180 is not 255.

180*1.25=225

51/36*180=255

$$225 \neq 255$$

Do you understand now?

Brandy don't worry about it, I had to do the calculation twice! I thought you were onto something massive there haha!

Well I find most of my errors in maths tend to be in the most fundamental aspects of it. Like say in the equation $a=2+b$ I will rearrange it to $\frac{a}{b}=2$ and silly things like that. I guess the moral of the story is to check over your work! If Cristo's story was boring I would hate to know what people think of mine!
