Hussein

Hussein owns 450000. He spent at the bookstore 2 over 9 to buy some books and tales. He paid 3 over 5 of his money to buy his math book. Then he paid his money to buy stories diagram ;
a. Calculate the remaining amount of money with Hussein?
b. Hussein lost 3 over 4 of the remaining money. Calculate the amount of money lost?

Result

a =  80000
b =  60000

Solution:

$x=450000 \ \\ a=x - \dfrac{ 2 }{ 9 } \cdot \ x - \dfrac{ 3 }{ 5 } \cdot \ x=450000 - \dfrac{ 2 }{ 9 } \cdot \ 450000 - \dfrac{ 3 }{ 5 } \cdot \ 450000=80000$
$b=\dfrac{ 3 }{ 4 } \cdot \ a=\dfrac{ 3 }{ 4 } \cdot \ 80000=60000$
