Question

Raahim gave ¼ of a pizza to his sister, another ¼ to his mother and 1/3 of the remaining to his father. What fraction of the pizza is left for his brother Saim?

Answer 1

`remaining = 1 - ( (1)/(4) + (1)/(4) ) \\ = (1)/(2) \\ fraction \: given \: to \: father = (1)/(3) * (1)/(2) \\ = (1)/(6) \\ pizza \: left \: for \: brother = (1)/(2) - (1)/(6) \\ = (1)/(3)`

Answer 2

tom ate 1/4 pizza, so that left him with 3/4 pizza.

Now that 3/4 is divided into 1/12 , so now he got 3/4 : 1/12

= 9 slices of 1/12 pizzas , or 9/12 of the original pizzas

Now it remained 1/6 or 2/12 of the original pizzas.

which mean, the amount of friends that got pizza are : 9 - 2 = 7 friends

hope this helps
