Ratios
Hi,

this is probably very basic, I have found examples on the web but they use simple numbers and it hasnt really helped.

Basically i have two array of numbers, the first array of numbers adds up to:

2567867 //lets say number of boys

and the second array adds up to:

56678 //say number of girls.

so would this as a ratio be 56678:2567867, how would this be simplified?

Any help would be great, thank you for your time.

Dear wollymath,

First you could find the greatest common divisor of these two numbers (say d). Then you could divide the numerater and the denomirator by d. This is the most simplified fraction you would get.

Do you need more assistance? If so don't hesitate to reply me.

Hi Sudharaka,

I found:

the greatest common divisor = 17.

Then ended up with:

3334:151051.

Is this correct?

Thanks for your help Sudharaka.

Dear wollymath,

Of course that is correct. You could check this with a scientific calculator.
