### Ratio question has my blood pressure in the red......-:)

Im on ratios in my working through the ccea gcse higher textbook and im really enjoying it.  ON ratios I sailed through the summary questions and exam questions without too much trouble and was happy I had a good grasp.....until.....this question stumped me.

Question: A prize is divided between three people P, Q and R.  If the ratio of P's share to Q's share is 3:1 and of Q's share to R's share is 2:5 , calculate the ratio of P's share to R's share.

The answer is 6:5 as per the book but I need someone to explain ....how...the steps to this answer is arrived at.    Many thanks for your patience with this old codger...

Hi;

Substitute in the first equation the value of Q = ( 2 / 5 R).

or 6:5

In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Thanks bobbym I'll have a good think about this.  I confess it's still not overly clear in my mind.

What do you need help on?
