If a pipe fills 25% of a tank in 1 hour, it means it fills 1/4 of the tank in that time. To find out how many hours it will take to fill the tank completely, you can use the formula: total hours = 1 / (fraction filled in 1 hour). In this case, total hours = 1 / (1/4) = 4 hours. Therefore, the pipe will fill the tank completely in 4 hours.
