Answer:
A D
Step-by-step explanation:
Answer and Explanation:
To find : Perform the indicated operations?
Solution :
Modular math is defined as

or 
Where, A is the dividend
B is the divisor
Q is the quotient
R is the remainder
The solution is 
Now, We perform same in every case
1) 
We can direct add the term,

Now, we divide 15 by 5 and see the remainder

Remainder is 0.
So, 
2) 
We can direct subtract the term,

Now, we divide -4 by 12 and see the remainder

Remainder is 8.
So, 
3) 
We can direct multiply the term,

Now, we divide 12 by 5 and see the remainder

Remainder is 2.
So, 
4) 
We can direct divide the term,

Now, we divide 0.5 by 5 and see the remainder

Remainder is 0.5.
So, 
2 1/3 + (-1 2/3)
2 1/3 - 1 2/3
7/3 - 5/3
2/3
