What is two sixths as a decimal?
2/6 can be simplified to 1/3 but this has no effect on the decimal equivalent which is 0.333333...... (with the number 3 going on indefinitely). This is said to be a recurring decimal number and is written with a line over the recurring portion to indicate that it is repeated indefinitely. In this case, the decimal number would be written 0.3 (with a line over the figure 3).

How do you change 0.121212 to fraction?
0.121212 = 121212/1000000 = 30303/250000 If 0.121212 is meant to indicate 0.12 recurring, then Let D = 0.12.. 100*D = 12.12.. Subtracting the first from the second, 99*D = 12 so that D = 12/99 = 4/33
Rewrite 0.5216216216... as a recurring decimal and explain how you do it please?
The question has already put the number in a recurring decimal form. It can be presented as 0.5216 with a line over the numbers 2,1 and 6 to indicate that those three numbers in that same sequence are repeated forever. This line is known as a vinculum. Earlier mathematics used dots above the number(s) to indicate those numbers that were recurring and this method is still seen and used.
