P6 question

There are twice as many sweets than pencils . If each of the girl recieved 1/6 of the mixed amount and each of the boy recieved 1/9 of the mixed amount how many boys and girls are there ?

  1. Answer: 1/9=2/18 (per boy)
    1/6=3/18 (per girl)

    Trial and error ( 3boys 4girls)
    ...
    2/18 x 3= 6/18
    3/18 x 4= 12/18

    Total 6/12+12/18= 18/18

    Proven 3 boys & 4 girls
