To find the value of the expression −6 4/9−1 1/3, we need to subtract the two numbers.
First, we need to convert the mixed numbers to improper fractions:
-6 4/9 = -6 * 9/9 + 4/9 = -54/9 + 4/9 = -50/9
-1 1/3 = -1 * 3/3 + 1/3 = -3/3 + 1/3 = -2/3
Now we can subtract the fractions:
-50/9 - 2/3
To subtract these fractions, we need to find a common denominator, which in this case is 9:
(-50/9) * (3/3) = -150/27
(-2/3) * (9/9) = -18/27
Now we can subtract the fractions:
-150/27 - 18/27 = -168/27
To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 3:
(-168/3)/(27/3) = -56/9
Therefore, the value of the expression −6 4/9−1 1/3 is -56/9.

Apologies for the mistake. Let's try solving it again.
To subtract mixed numbers, we'll follow these steps:
1. Subtract the whole numbers.
2. Subtract the fractions.
Let's begin:
-6 4/9 - 1 1/3
Step 1: Subtract the whole numbers: -6 - (-1) = -6 + 1 = -5
Step 2: Subtract the fractions: 4/9 - 1/3
To subtract fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 9.
Multiplying 1/3 by 3/3 gives us 3/9.
So, now we have 4/9 - 3/9 = 1/9.
Putting it all together, the expression -6 4/9 - 1 1/3 equals -5 1/9 or -5 1/9 as a mixed number.
425.82 − (−120.75)
To find the value of the expression 425.82 − (−120.75), we subtract the second number from the first number.
425.82 − (−120.75) = 425.82 + 120.75
Now, we can add these two numbers:
425.82 + 120.75 = 546.57
Therefore, the value of the expression 425.82 − (−120.75) is 546.57.
7.829 − 3.21
To find the value of the expression 7.829 − 3.21, we subtract the second number from the first number.
7.829 − 3.21 = 4.619
Therefore, the value of the expression 7.829 − 3.21 is 4.619.
