Answer:
9
Step-by-step explanation:
All you have to do is follow this order while working a problem!
Example 1:
If a = 4 and b = 5, what is ab – 2b?
Since there are no parentheses or exponents,
you first plus in the values for a and b and multiply those together.
(4 ´ 5) You get 20.
Then, you multiply 2b or (2 ´ 5 )which gives you 10.
Last, you subtract the second answer from the first (20 -10),
which gives you 10!
Example 2:
Evaluate 6x / 4 when x = 6.
Because multiplication and division are equal in the order of operations, you solve the problem by reading it from left to right like one would read a book.
6 x 6 = 36.
You then divide that number by 4.
The correct answer is 9.

Answer:
5/8
Step-by-step explanation:
There are 8 intervals, the tack ends at the 5th interval, so 5/8
Reduce the expression 54/12 by cancelling the common factors
9/2
the result of division 9/2 is 4 with a remainder of 1
