Answer:
2 
Step-by-step explanation:
for question a)
It would be easier if you converted these to improper fractions (currently it is in the form of a proper fraction)
to convert to improper fraction, you would multiply the denominator (bottom no. of fraction) by the whole number , then add that with the numerator (top no. of fraction) and put the whole thing over the denominator.
E.g.
7 
= 7x4 + 1 = 29
Thus, improper fraction would be 
do same thing for other one
thus , 
now,
-
however, you can't do this as the denominators are not the same, so multiply them by a number which would give the a common denominator (20 would be the best option for common denominator)
= 
convert back to mixed number

Answer:
B.It takes more than 12 loads to wash 9 bins of towels.
Step-by-step explanation:
The function f(x) gives the number of loads required when there are x bins of towels to be washed.
f(x)=Number of loads
x=Bins of towels
Therefore in the inequality f(9)>12
- Number of loads=12
- Bins of towel =9
If f(9)>12, it means Number of loads is more than 12.
f(9)>12 therefore tells us that it takes more than 12 loads to wash 9 bins of towels.
The correct option is B
