Answer:
option 1
Step-by-step explanation:
the square root of 6 is 2.44949, rounded it's 2.4
the square root of 42 is 6.48074, rounded it's 6.5
in option 1 the 6 is placed after the 2 because it is point 4, not quite 2 but a bit bigger than 2 but less than 3.
same thing for 42, it is placed after 6 because it is not quite 6 but not over 7. i hope this helped
