Respuesta :
The 7/20th fraction of his lotto earnings is remaining.
Let us say the man has $100
Money spent on luxury cars = 2/5 of the money
Money spent on luxury cars = 2/5 * 100 = $40
Money spent on buying a house = 1/4 of the money
Money spent on buying a house = 1/4 * 100 =$25
Money left with the man = 100-40-25 = $35
$35 is what fraction of $100?
$35 is 35/100 fraction of $100.
35/100 = 7/20
So, the 7/20th fraction of his lotto earnings is remaining.
