Question

A mother takes 55 cm at each step; her child, or at each step, takes 25 cm. > If they start walking together on the same foot, after how many meters will they step together again?​

Answer 1

$\huge{\fbox{\pink{Answer:-}}}$

Here, the required minimum distance will be equal to the LCM of measures of their steps.

Step measure of $\huge{\purple{Mother}}$ = 55 cm

Step measure of her $\huge{\purple{Child}}$ = 25 cm

LCM of 55, 25

LCM = 275

Hence, after 275 cm they will step together again.

Answer 2

Here, the required minimum distance will be equal to the LCM of measures of their steps.

Step measure of \huge{\purple{Mother}}Mother = 55 cm

Step measure of her \huge{\purple{Child}}Child = 25 cm

LCM of 55, 25

LCM = 275

Hence, after 275 cm they will step together again.
