Answer 1

Answer:

here is ur ans......

Step-by-step explanation:

Given :- their steps measure 80 cm , 85 cm and 90 cm.

we have to find the L.C.M. of the measure of their steps i.e. 80 cm , 85 cm and 90 cm to calculate the required distance each should walk.

L.C.M. of 80 cm , 85 cm and 90 cm

80 = 2^4 × 5

85 = 17 × 5

90 = 2 × 3 × 3 × 5

L.C.M. of 80 , 85 and 90

2^4 × 3 × 3 × 5 × 17

L.C.M. of 80 , 85 and 90 = 12240 cm

hence , the minimum distance each should walk so that all can cover the same distance in complete steps is 12240 cm .
