Repeating decimals(Multiplication and division) work out by steps please
 (a.)o.333...x6/7
 Find the fraction of the repeating decimal first.
 n = 0.333...
 10n = 3.333...
 -1n = 0.333...
 ----------- -------- Subtract
 9n = 3
 n = 1/3
 -----
 (1/3)*(6/7) = 3/7
 =========== =========== ==== 
 (b.)0.888...divided by 2/9
 Similar to (a), you try it.
 ----------- --
 (c.) 0.2727...x 8/11
 n = 0.2727...
 100n = 27.2727...
 - 1n = -0.2727...
 ----------- -----
 99n = 27
 n = 3/11
 =========== == 
 (d.) 0.1212.. divided by 5/3
 =========== =====
 Similar to (c)
 = 0.1212... times 3/5
