Are repeating decimal irrational?
No.Repeating decimals are rational.To convert a repeating decimal to a fraction, put the repeating digit(s) over the same number of 9s and simplify:examples.0.333...It has one repeating digit (3) so put it over one 9 (9) to get 3/9 which can be simplified by dividing top and bottom by 3 (the hcf of 3 and 9) to get 1/3. Thus: 0.333... = 1/30.181818...It has two repeating digits (18) so put them over two 9s (99) to get 18/99 which can be simplified by dividing top and bottom by 9 (the hcf of 18 and 99) to get 2/11. Thus: 0.181818.... = 2/11
How do you put three seventh into decimal form?
To put 3/7 into decimal form, you would divide 3 by 7, which would be 0.428571... repeating those 6 digits forever; normally it would be approximated by being rounded to, say, 2 or 3 decimal places, that is 3/7 ≈ 0.43 or 0.429
How do you turn a whole mixed number into a decimal?
divide the numerator by the denominator, and round to the nearest tenth or hundredth, whatever is best. Ex. 1 1/2 = 1.5 since 1 divided by 2 is .5, make the new number 1.5. if the number is 1 1/3, then the decimal would be 1.33333..... so then you would round it to the nearest tenth (1.3) or the nearest hundredth (1.33) and then put a repeating bar over the decimal.
