6
5 over 6
(81/10) - (25/6)
(243/30) - (125/30) = 118/30 = 3 28/30 = 3 14/15
To subtract fractions, follow these steps:
Step 1: Make sure the denominators (the bottom numbers) are the same. If they are not the same, find the least common multiple (LCM) of the denominators and convert both fractions to have that denominator.
In this case, the LCM of 10 and 6 is 30. So, we need to convert the fractions to have a denominator of 30.
8/10 = (8 * 3) / (10 * 3) = 24/30
2/6 = (2 * 5) / (6 * 5) = 10/30
Now, the fractions have the same denominator, which is 30.
Step 2: Subtract the numerators (the top numbers) while keeping the denominator the same.
24/30 - 10/30 = (24 - 10) / 30 = 14/30
Step 3: Simplify the fraction, if possible. In this case, both the numerator and denominator are divisible by 2:
14/30 = (14/2) / (30/2) = 7/15
So, the answer is 7/15.
