Question

1.66666666667 rounded to the tenth

Answer 1

To round a number to the tenth, any number greater than or equal to 5 will round up and anything less than 5 round down.
So, the number after the tenths place is a 6 which is greater than 5, so you would round up.
So, your answer would be 1.7

Answer 2

Hey there! :D

The tenth place is where the first 6 is, so:

1.666666666667=

1.7 because 6>5

I hope this helps!
