  1. 2/5 on transport, leaving 3/5
    1/5 of that is 3/25 on sweets, leaving 12/25
    1/3 of that is 4/25 on movies, leaving 8/25
    so,
    8/25 x = 13.00

    I suspect a typo

  3. 2/5 on transport.Remiander 3/5
    1/5 of 3/5=3/25=0.6/5 on sweets remiander 2.4/5,
    1/3 of 2.4/5=2.4/15=0.8/5 on movies.Remiander 1.6/5=GH¢13.00
    1.6/5÷0.8/5=GH¢13/x
    0.32/0.16=GH¢13/x
    2x=13
    x=GH¢6.50. 0.8/5=GH¢6.50
    0.32+0.16 =13.00+6.50
    0.48=GH¢19.50 2.4/5=GH¢19.50
    2.4/5÷0.6/5=19.50/x
    0.48/0.12=19.50/x
    4x=19.50. x=4.875
    2.4/5+0.6/5 =19.50+4.875
    3/5 =GH¢24.375
    3/5÷2/5=24.375/x
    0.6/0.4=24.375/1.5
    x =16.25
    2/5=GH¢16.25
    3/5+2/5 =24.375+16.25
    5/5=40.625
    1=GH¢40.625
    Her pocket money is GH¢40.625.
