Sam spent 1/3 of his time playing soccer and 4/9 of his time doing homework.he pent the rest of his time playing computer games.how much of his time did Sam spend playing computer games?
Answer provided by our tutors
let 'x' be the total time Sam had
1/3 of x he spent on playing soccer
4/9 of x he spent on homework
the rest of the time is x - (1/3 + 4/9)x = x(1 - (1/3 + 4/9)) = x(9 - (3 + 4))/9 = x*(2/9)
Spam spent 2/9 of his time playing computer games.
