Notes from 2 Sept
When simplifying ratios treat like a fraction and divide each part by the HCF ie.
15 : 24 divide both by 3 to get 5 : 8
When splitting an amount by a ratio add the parts then divide the amount by the total parts, then multiply each bit by the answer - make sense?! An example should help:
Divide $85 in the ratio 2 : 3.
So 2 + 3 = 5 and 85 divided by 5 is 17
17 x 2 = 34 and 17 x 3 = 51
so the ratio is $34 : $51
