Answer:
1 1/18
Step-by-step explanation:
- First things first, write the problem so you can understand what you need to solve. 1 5/9 - 1/2 = ?
- After you write the problem, write the problem again, only this time, make your proper denominator ( 1 5/9 ) into an improper fraction ( 14/9 ).
- Now try and find a common denominator. For this problem 18 is the common denominator since 9 x 2 = 18. In some cases you don't want to make it to hard on yourself by having a big common denominator so it is more easier to simplify your answer at the end. You need to also change your numerator the same way how you changed the denominator but do not find a common numerator, you already have the common denominator so just multiply to get your new numerator
- Rewrite your problem again using the improper fraction. Old fraction : 14/9 - 1/2 = ? New Fraction : 28/18 - 9/18 = ?
- Now it is time to subtract. Subtract your newest problem you wrote down and you might or might not have an improper fraction. If you do not have an improper fraction you are done. If you want you can make sure it is in the simplest form it can possibly be in.
- If you do have an improper fraction, it is time to make that into a proper fraction. You will have to subtract the fraction from the whole number it makes. Answer : 19/18 New Proper Fraction: 19/18 - 18/18 = 1
- Your answer now is 1 1/18.
(Note) : Sometimes you will have an answer that can be simplified even more. It is optional if you want to simplify your answer but it is necessary you follow all of the steps above this note if you want to solve this problem.
