Question

salary of $4500, I kept 1/3 as savings.out of the remaining money, I spend 50% on food and 20% on house rent. How much do I spend on food and house rent

Answer 1

savings: (4500)(1/3)=1500

food: (4500)(2/3)(1/2)=1500

house rent: (4500)(2/3)(1/5)=600

Answer 2

In this kind of math, you do things in order and you will be all fine.

 

First one is savings.  Translate English to math:

"1/3 of Salary is savings"

 

The English word "of" translates to "multiply" in math.  the English word "is" translates to "equal".  Therefore

 

1/3 * $4500 = "savings"

 

So you know savings is $1500.

Of that $1500, 50% is food.

 

$1500 x 50% = "food"

$1500 x 0.5 = $750 = "food"

 

Of that $1500, 20% is rent.

 

$1500 x 20% = "rent"

$1500 x 0.2 = $300 = "rent"

 

 

The amount spent for food and rent are $750 and $250 respectively.
