Anything minus itself equals zero.
In order to add or subtract fractions, the denominator (bottom number) has to be the same. In order to make it the same, you find the LCM and multiply the fraction by whatever is necessary to make the denominator the LCM. FOR EXAMPLE: 1/3 + 2/5 The LCM of 3 and 5 is 15. To make the 3 in 1/3 15, you multiply the whole fraction by 5 over 5 (it simplifies to 1 so you aren't really changing the fraction by multiplying it by 1). 1/3 * 5/5 is 5/15 You multiply 2/5 times 3 over 3 using the same principle 2/5 * 3/3 is 6/15 NOW you can add 5/15 and 6/15 to get 11/15.
8/3 is a fraction.
12/14, 18/21
16/25 - 10/25 = 6/25
6/7 - 2/3 = 18/21 - 14/21 = 4/21
To subtract fractions, you need a common denominator. In this case, the common denominator is 7. So, 8/14 is equivalent to 4/7. Subtracting these fractions gives us 0. Hence, 4/7 minus 8/14 equals 0.
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

If the fractions have the same denominator, add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible. If the fractions have different denominators, find the LCM of the denominators and convert the fractions to equivalent fractions with like denominators. Then add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible.
5/8 - 1/4 = 5/8 - 2/8 = 3/8 (make all fractions equivalent fractions with a common denominator - in this case, a common denominator of 8 - and then subtract the numerators).
Use the distributive property: 17pi/6 - 2pi = (17/6 - 2) pi. Now, just subtract the fractions as you normally would.
To subtract fractions, the denominators (bottom numbers) must be equal; so first convert the fractions into equivalent fractions with the same denominator. Then the numerators (top numbers) are subtracted and the resulting fraction simplified: 2/9 - 5/6 = 4/18 - 15/18 = -11/18
To subtract fractions, the denominators (bottom numbers) must be equal; so first convert the fractions into equivalent fractions with the same denominator. Then the numerators (top numbers) are subtracted and the resulting fraction simplified: 7/13 - 1/18 = 126/234 - 13/234 = 113/234
To subtract fractions, the denominators (bottom numbers) must be equal; so first convert the fractions into equivalent fractions with the same denominator. Then the numerators (top numbers) are subtracted and the resulting fraction simplified: 2/3 - 2/5 = 10/15 - 6/15 = 4/15
To subtract fractions, the denominators (bottom numbers) must be equal; so first convert the fractions into equivalent fractions with the same denominator. Then the numerators (top numbers) are subtracted and the resulting fraction simplified: 5/6 - 1/4 = 10/12 - 3/12 = 7/12
to subtract (or add) fractions you need tohave a common denominator 7/12 - 1/3 = 7/12 - 4/12 = 3/12 = 1/4
To subtract fractions, you need to find a common denominator. The common denominator for 10 and 4 is 20. So, rewriting the fractions with a denominator of 20, we get 6/20 - 5/20 which equals 1/20.
