what do you think i am, a calculator 0.7 repeating
Put the repeating part over as many 9's as there are parts that are repeating. For example, if it is just a 7 that is repeating, then it is 7/9, but if it is a 45 that is repeating (as in .45454545...), then it is 45/99. A 2376 that repeats is 2376/9999. Try it out on your calculator, and you'll see that 7/9 is .77777...
Why do people ask mathematics questions on a computer that has a calculator on it?? 16.6 (the last six is repeating)
You can't 'get rid' of them - if the problem creates them in the answer. You can, however, manually round the answer up or down to a more manageable figure.
let x=.5 repeating. because .5 repeating has one digit repeating, mulitply each side of x=.5 repeating by 10 to the first power, or 10. then 10x=5.55 repeating. subtract one x from 10x, so since each x is .5 repeating, 5.55 repeating minus .5 repeating is 5. that means 9x=5. then its x=9/5, which is your answer. if possible, simplify. so the answer is .5555 repeating is equivalent to the fraction 9/5. Doesn't 9/5 = 1.8? I mean if you use your calculator to do the check the math it doesn't make sense that a top-heavy fraction can be less than one, does it not?
