Fraction P6 2009 SA1 P2 RGS Q16

16. In a math competition, participants can obtain 4 possible awards: Gold, Silver, Bronze and Participation. 3/7 of the participants obtained Gold awards, 1/4 of them obtained Silver awards, and 1/6 of them obtained Bronze awards. Given that there were less than 100 participants taking the competition,
a) How many participants obtained the awards for Participation? [3]
b) How many more participants obtained Gold awards than Bronze awards? [2]


3/7 x 12/12 = 36/84
1/4  x 3/3 x 7/7 = 21/84
1/6 x 2/2 x 7/7 = 14/84

84 – 36 – 21 – 14 = 13

a) 13 participants obtained the awards for Participation.


36 – 14 = 22

b) 22 more participants obtained Gold awards than Bronze awards.
