Question

Table

Answer 1

Before budget change :

Maintenance = 1 - 1/3 - 1/3 - 1/4 = 1/12

After budget change :
 
Maintenance = 1 - 1/3 - 1/8 - 1/4 = 7/24

Difference in budget for maintenance = 7/24 - 1/12 = 5/12

Answer 2

Answer:

$\frac{5}{24}$

Step-by-step explanation:

Previous year table .

Food - $\frac{1}{3}$

Housing - $\frac{1}{3}$

Medical Care - $\frac{1}{4}$

So, total =$\frac{1}{3}+\frac{1}{3}+\frac{1}{4}$= $\frac{11}{12}$

Since we are given that  the remaining portion of the budget will be for maintenance expenses.

So, maintenance expenses = $1-\frac{11}{12}=\frac{1}{12$

Present year table

Food -$\frac{1}{3}$

Housing -$\frac{1}{8}$

Medical Care - $\frac{1}{4}$

So, total =$\frac{1}{3}+\frac{1}{8}+\frac{1}{4}=\frac{17}{24}$

Since we are given that  the remaining portion of the budget will be for maintenance expenses.$1-\frac{17}{24}=\frac{7}{24}$

The difference between the fraction of the budget for maintenance this year and last year = 7/24 - 1/12 = 5/24

Hence the difference between the fraction of the budget for maintenance this year and last year is 5/24
