Answer 9

ok so you can start like this


100x = 42.4242...... this is repetitive.
x = 0.4242.... thats when you move the decimal over

Answer 10

next step

Answer 11

your subtracting the top which will be 99 since, 100x is now 99 because x always equals 1 so 100 - 1 = 99 and then the bottom which is 42 from moving the decimal

Answer 12

So is the answer C?
