slove x/13 < 4/5

To solve the inequality x/13 < 4/5, we can begin by multiplying both sides of the inequality by 13 to eliminate the fraction:

(x/13) * 13 < (4/5) * 13
x < 52/5

Next, we can simplify the right-hand side:

x < 10.4

Therefore, the solution to the inequality x/13 < 4/5 is x < 10.4.
