Step-by-step explanation:
54/125 fraction of pie is left.
Step-by-step explanation:
Sana has 4/5 of the pie.
She ate 2/5 of the pie.
Therefore amount of pie left-(4/5) ×(1-(2/5)) =(4/5) (3/5) =12/25.
Again Sana's sister ate (1/10) of the remaining.
Therefore fraction of pie left is =(12/24) -(1-(1/10)) (12/25) x(9/10) =108/250=54/125.
