Answer:
multiplicative inverse of 1/2 is 2
Step-by-step explanation:
The multiplicative inverse of a/b is b/a
Because 
To get multiplicative inverse of any fraction we take the reciprocal of that fraction
Multiplicative inverse of 
2/1 or 2 are same
so multiplicative inverse of 1/2 is 2
Answer:
Step-by-step explanation:
so he worked 132 hrs in 4 weeks..he worked 6 days per week....

Answer:
The greatest number of the books that could have been borrowed during the week is 36
Step-by-step explanation:
Let's create an equation which represent this problem, where will rest the book borrow and add the book returned to the 40 initial amount of book on Monday, to get the 22 book in the shelf on Saturday morning
40 (book on the shelf on Monday) - x (book borrowed) + 0.5 * x (50 % of the book was returned before Saturday) = 22 (books in the shelf on Saturday morning)
40 - x + 0.5 * x = 22
40 - 0.5*x = 22
18 = 0.5 * x
18/0.5 = x
36 = x
The amount of borrowed books is 36
