Ok, lets start with the top.
7/8 + (-2/3)
Thats equal to
7/8 - 2/3
The common denominator will be 24
21/24 - 16/24
Subtract
5/24
Now, to divide you multiply by the reciprocal, so
5/24 / 5/6
Becomes
5/24 * 6/5
Cross simplify and get your answer
1/4
The first one is distributive property
I think the 2nd and last are associative
and the last is commutative
Answer:
P (2 and then odd number) = 
Step-by-step explanation:
Probability refers to chances of occurrence of any event.
A number cube is rolled twice.
Possible outcomes are as follows:






Total number of outcomes = 36
Favorable outcomes include outcomes with 2 and then odd number.
So,
Favorable outcomes are 
Number of favorable outcomes = 3
Probability is equal to number of favorable outcomes divided by total number of outcomes.
Therefore,
P (2 and then odd number) = Number of favorable outcomes ÷ Total number of outcomes


You basically just repeat the same steps of a regular 2-3 ditget division
