Question

Emma is planting rows of seeds. In the first row, she places beetroot seeds nine cm apart. After what distance will a beetroot seed be in line with a lettuce seed again?

a. 18 cm
b. 27 cm
c. 36 cm
d. 45 cm

Answer 1

The distance at which a beetroot seed will be in line with a lettuce seed again is 27 cm.

Step-by-step explanation:

To determine the distance at which a beetroot seed will be in line with a lettuce seed again, we need to find the least common multiple (LCM) of the distances between two beetroot seeds and two lettuce seeds. The distance between two beetroot seeds is 9 cm, and the distance between two lettuce seeds is 27 cm. The LCM of 9 cm and 27 cm is 27 cm.

Therefore, after a distance of 27 cm, a beetroot seed will be in line with a lettuce seed again.
