Answer:
First one should be 3 1/4 or 3.25
Step-by-step explanation:
What you do is count up the lines so in this case we have 4 lines so we do 100/4 = 25 so each line is 0.25 or 1/4 and since it's after 3 it should be 3 1/4 or 3.25

the idea being, you multiply the "x" by some power of 10 that moves the repeating part to the left of the decimal point and the split it like above.
