Answer 2

To subtract fractions, you first have to get them to have the same denominators. The least number that both 5 and 9 go into is 45. Multiply 4/5 by 9 to get 36/45, then multiply 1/9 by 5 to get 5/45. Once you get them to have the same denominator, you can subtract the fractions. When you subtract fractions, you subtract the numerators, but leave the denominators. 36-5=31. Once you subtract the numerators, your fraction would become 31/45. To simplify the fraction, you have to find a whole number that goes into both 31 and 45. If there is no number then it is already in simplest form. Your answer would be 31/45.
