Two rulers

We have two rulers. Scale interval on first rulers are a spaced 1 cm and on second spaced 15 mm. Rulers are attached to each other so that they match initial divider commas. What next dividers commas coincide? Find at least three cases.

Correct result:

a =  30 mm
b =  60 mm
c =  90 mm

Solution:

1 cm=10 mm 10=25 15=35 LCM(10,15)=235=30  a=LCM(10,15)=30 mm
b=2 a=2 30=60 mm
c=3 a=3 30=90 mm



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
