9 Five girls took part in a race ,Alison finished before Betty but behindClair, Diane finished before Emma but behind Betty .in what order did they finish. 10 For every 5 tiddlywinks shot in the red target ,6 landed in the blue and for every 6 in the blue there were 7 in the yellow .The total was 108 how many finished in the red target .can anyone give me any clues how to work out these .Thanks for any help.
Your tiddlywinks question is an algebra problem.
5 x Red + 6 x Blue + 7 x Yellow = 108 or
5R + 6B + 7Y = 108
Add 5 + 6 + 7 = 18.
108 divided by 18 = 6
So out of the 108 there were
5 x 6 Red, 6 x 6 Blue and 7 x 6 Yellow.
