Question

For number 19 I don’t get it, there’s nothing wrong with it(i think) please help me

Answer 1

-7/11 is not -.63 with the three repeating

If u put it into a calculator it is -.63636363
( so the line should be over both the 6 and the 3, because that is what is repeating)

Answer 2

The repeating sign is just over the 3 and needs to be of the 6 and the 3
