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
Lizzy spends 2/5 of her pocket money on transportation, 1/5 of the remainder on sweets and 1/3 of what still remains on movies. If she has ¢ 13.00 left, how much is her pocket money?

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
