The classroom

The classroom is 9 meters long. The width of the classroom is smaller and can be passed in equally long steps of 55 CM or 70 CM. Determine the width of the classroom.

Correct answer:

b =  7.7 m

Step-by-step explanation:

a=9 m 55=511 70=257 LCM(55,70)=25711=770  x=LCM(55,70)=770 cm b<a b=x m=x/100  m=770/100  m=7.7 m=7.7 m
