A queen termite that is 5mm long how many can fit on a 50 cm ruler?

To determine how many 5 mm queen termites can fit on a 50 cm ruler, first convert 50 cm to mm, which equals 500 mm. Then, divide the total length of the ruler by the length of one termite: 500 mm ÷ 5 mm = 100. Therefore, 100 queen termites can fit on a 50 cm ruler.
