 The required simplified fraction is

Step-by-step explanation:  We are given that in a grocery store there are 4 self-checkout lines and 8 lines with cashiers.

We are to find the ratio of the number of lines with cashiers to the number of self-checkout lines.

Let n represents the number of lines with cashier and m represents the number of self-checkout lines.

Then, we have

n = 8 and  m = 4.

Therefore, the required ratio of the number of lines with cashiers to the number of self-checkout lines is given by

Thus, the required simplified fraction is
