- 12 2/3 - 8 5/5?
To subtract these fractions, we first need to convert them to improper fractions.
12 2/3 is equal to (12 x 3 + 2) / 3 = 38/3.
8 5/5 is equal to (8 x 5 + 5) / 5 = 45/5.
Now we can subtract them:
38/3 - 45/5
To find a common denominator, we need to find the least common multiple (LCM) of 3 and 5, which is 15.
38/3 = 38/3 x 5/5 = 190/15
45/5 = 45/5 x 3/3 = 135/15
So, the expression becomes:
190/15 - 135/15
Now, since the denominators are the same, we just subtract the numerators:
190 - 135 = 55
Therefore, the final answer is 55/15, which can be simplified to 11/3 or 3 2/3.
To subtract 12 2/3 - 8 5/5, we need to convert the mixed numbers to improper fractions.
First, let's convert 12 2/3 to an improper fraction:
12 * 3 = 36 + 2 = 38. So 12 2/3 is equal to 38/3.
Next, let's convert 8 5/5 to an improper fraction:
8 * 5 = 40 + 5 = 45. So 8 5/5 is equal to 45/5.
Now, we can subtract the fractions:
38/3 - 45/5
To subtract fractions, we need to find a common denominator. In this case, the least common multiple of 3 and 5 is 15.
Now, let's rewrite the fractions with the same denominator:
38/3 = (38 * 5) / (3 * 5) = 190/15
45/5 = (45 * 3) / (5 * 3) = 135/15
Now we can subtract:
190/15 - 135/15 = (190 - 135) / 15 = 55/15
Finally, we can simplify the resulting fraction:
55/15 = 11/3
So, the answer is 11/3.
