First, write it as a mixed number by changing the decimal part to a fraction. Here's how you do that: Change 0.444... to a fraction. Let n = 0.444... Multiply both sides by 10 10n = 4.444... Now subtract n from 10n 10-n = 4.444... - 0.444... = 4, so: 10n-n = 9n = 4 Divide both sides by 9 9n/9 = 4/9 n = 4/9 But n = 0.444..., so 0.444... = 4/9 The mixed number is: 3 4/9 Now if you want this as an improper fraction, then: 3 4/9 = 31/9 Check this answer on your calculator.
