-6 4/9 - 1 1/3
To subtract mixed fractions, you need to convert them to improper fractions first.
-6 4/9 = -61/9
1 1/3 = 4/3
Now subtract the fractions:
-61/9 - 4/3
To add or subtract fractions, they must have a common denominator. In this case, the common denominator is 9 (3 can be multiplied by 3 to get 9).
-61/9 - 4/3 = -61/9 - (4/3)(3/3) = -61/9 - 12/9 = (-61 - 12)/9 = -73/9
Therefore, -6 4/9 - 1 1/3 = -73/9
-6 4/9 = -61/9
1 1/3 = 4/3
Now subtract the fractions:
-61/9 - 4/3
To add or subtract fractions, they must have a common denominator. In this case, the common denominator is 9 (3 can be multiplied by 3 to get 9).
-61/9 - 4/3 = -61/9 - (4/3)(3/3) = -61/9 - 12/9 = (-61 - 12)/9 = -73/9
Therefore, -6 4/9 - 1 1/3 = -73/9

What is 4 - 1 1/4 + 1/2?
To solve the expression 4 - 1 1/4 + 1/2, we need to convert the mixed number 1 1/4 to an improper fraction and find a common denominator to combine the fractions.
1 1/4 as an improper fraction is (4 * 1 + 1)/4 = 5/4.
Now, let's find a common denominator for 4, 5/4, and 1/2. The common denominator will be 4.
Rewriting the expression with the common denominator:
4(4/4) - 5/4 + 2/4 = 16/4 - 5/4 + 2/4.
Now, subtract the fractions:
16/4 - 5/4 + 2/4 = (16 - 5 + 2)/4 = 13/4.
So, 4 - 1 1/4 + 1/2 equals 13/4, or it can be expressed as the mixed number 3 1/4.
1 1/4 as an improper fraction is (4 * 1 + 1)/4 = 5/4.
Now, let's find a common denominator for 4, 5/4, and 1/2. The common denominator will be 4.
Rewriting the expression with the common denominator:
4(4/4) - 5/4 + 2/4 = 16/4 - 5/4 + 2/4.
Now, subtract the fractions:
16/4 - 5/4 + 2/4 = (16 - 5 + 2)/4 = 13/4.
So, 4 - 1 1/4 + 1/2 equals 13/4, or it can be expressed as the mixed number 3 1/4.
