If your share in a 40,000 inheritance is 3/4 how much money will you receive

To start, what is 3/4 ?  Think of it as you have $1.00 (4 quarters) now you only have 3 quarters= 75 cents. 
Therefore, what is 75% of 40,000?
Multiply 75 by 40,000=3,00,000 
divide 3,000,000 by 100=30,000
* if your allowed to use calculators, its simple:
75/100 x 40,000= 30,000

You will receive a $30,000.00 inheritance.
