If n is an integer , write each öf the following in the simplest form i^4n+29

Here it is: -7/3= -2 1/3 and 9/-4= -2 1/4
Inorder to add these two mixed numbers you would have to find the lowest common denominator (lcd). For this problem the the lcd = 12.

-2 1/3 = -2 4/12 and -2 1/4 = -2 3/12

Therefore, -2 4/12 + -2 3/12 = -4 5/12 ( you are able to add both mixed numbers sinse the lcd are in common)

#2 Any number which can be expressed as a whole number is classified as an integer.

Definition: The set of integers consists of the positive integers, negative integers, and zero.
{...-3,-2,-1,0, 1, 2, 3,}

Therefore, -81, 12/3=4, and 18/9 are the only numbers that qualify as an integer

72 is the mode because it shows up the most number of times
