Answer:
11 / 36
Step-by-step explanation:
By taking the LCM of the denominators ( 9, 12, 6)
We will get the total number of parts (total salary)
Therefore LCM = 36
Now
4/ 9 = 16/ 36 out of 36 he spends 16 for food
1/ 12 = 3/ 36
1/6 = 6/ 36
Savings = total salary - expenditure
= 36 - ( 16+ 3 + 6)
= 11 parts
Fraction = 11 / 36
