The expression to find the perimeter of a rectangle is 2(length + width). What is the perimeter, in units, of a rectangle of length fraction 1 over 7 unit and width fraction 1 over 2 unit?

P = 2(L + W)
L = 1/7
W = 1/2

P = 2(L + W)
P = 2(1/7 + 1/2)
P = 2(2/14 + 7/14)
P = 2(9/14)
P = 18/14 which reduces to 9/7 or 1 2/9 <==
