Re: [Math4u] Re: Does fraction mean division?

A fraction is represented by a ratio of two numbers, but not all ratios are fractions. A fraction is a single quantity.

hello,

"Fractions result from INEXACT DIVISION, when we view the remainder as a ratio of the divisor. "

19 divid by 8 = quotient 2 and the remainder 3

so the ratio 3 : 8  is equal to the fraction 3/8 isn't it?

another example :

35 divided by 6 = quotient 5 and the remainder 5

so the ratio is  5 : 6 and the fraction is 5/6

my question is :

when I see the fraction as for example : 9/14 I can quickly say

that is a ratio  9 :14  and this ratio is from some division where the remainder is 9 and the divisor is 14.

How to find this fraction?

if  Q is the quotient of this division , I can say that 

Q x 14+9= the dividend.

but that didn't give the concret division
