Question

How to make1.4 into a fraction (show me how to work problem)?

Answer 1

1.4 = 14/10

14/10 = (7*2)/(5*2)

(7*2)/(5*2) = 7/5

7/5 = 5/5 + 2/5 = 1 2/5

Answer: 7/5 or 1 2/5

Answer 2

You know that you begin your fraction with a 1.  SInce the .4 is in the 1/10th position, you make it 4/10.  Now, you can reduce it b/c they are both divisible by 2.  So your divide both numbers by 2 and you have

1 and 2/5

Answer 3

First write 1.4 as a fraction by inserting a 1 in the denominator place.  Now it's 1.4/1.  Now move the decimal place of the numerator and denominator one place to the right so you can get rid of the decimal.  Now it's 14/10.  14/10 is an improper fraction and can be simplified.  If simplified without it being a mixed number it is 7/5.  My teacher usually tells me to leave it improper if you're going to use it again, but if not you should write it as a mixed number as the final answer.  As a mixed number, 7/5 would be 1 and 2/5.
