Question

Three boys step together from the same spot. Their steps measure 63 cm ,70 cm and 77cm respectively. What is the minimum distance each should cover so that all can cover the distance in complete steps

Answer 1

Answer:

Hey mate, you can understand that the question is related to LCM

so, you need to find their factors.

7|63,70,77

3|9,10,11

5|3,10,11

 |3,2,11

⇒7 x 3 x 5 x 3 x 2 x 11

⇒6930 cm

∴ If they all want to cover the distance, then they should walk for 63.90 m.

Please mark me as brainliest

another technique is that since they are consequent multiples of 7, you can multiply them and divide it by 7²(49).
