John's monthly salary is $810. He spends 5/9 of it on rent, 1/3 of it on food and saves the rest. How much money does he save in a year?

$1080

Step-by-step explanation:

monthly salary = $810

money spent on rent = 810 × 5/9 = $450

money spent on food = 810 × 1/3 = $270

money saved in a month = monthly salary - (money spent on [rent + food])

                                           = 810 - (450 + 270)

                                           = 810 - 720 = $90

money saved in a year = money saved in a year × 12

                                                           90 × 12 = $1080

                                             OR

monthly salary = $810

yearly salary = 810 × 12 = $9720

money spent on rent = 9720 × 5/9 = $5400

money spent on food = 9720 × 1/3 = $3240

money saved in one year =

yearly salary - (money spent on [rent + food] in an year )

                                           = 9720 - (5400 + 3240)

                                           = 9720 - 8640 = $1080
