Answer 2

To solve the expression, let's take it step by step:

Step 1: Add -6, 54, and -2 -6 + 54 - 2 = 48

Step 2: Add 7/9 and 2/46 To add fractions, we need a common denominator. The least common multiple (LCM) of 9 and 46 is 414. So, let's convert both fractions to have a denominator of 414.

(7/9) = (7/9) * (46/46) = 322/414 (2/46) = (2/46) * (9/9) = 18/414

Now, add the fractions: (322/414) + (18/414) = (322 + 18) / 414 = 340 / 414

Step 3: Subtract 2 7/225 To subtract a mixed number, convert it to an improper fraction first:

(2 7/225) = (2 * 225 + 7) / 225 = (450 + 7) / 225 = 457/225

Now, we subtract: 340/414 - 457/225

To subtract fractions, we also need a common denominator. The LCM of 414 and 225 is 18,450. So, let's convert both fractions to have a denominator of 18,450.

(340/414) = (340/414) * (45/45) = 15,300/18,450 (457/225) = (457/225) * (82/82) = 37,474/18,450

Now, subtract the fractions: (15,300/18,450) - (37,474/18,450) = (15,300 - 37,474) / 18,450 = -22,174 / 18,450

The final result is -22,174 / 18,450, which can be further simplified if needed.
