Answer 2

To solve the expression -2 4/5 - (-7 2/9), we need to simplify the subtraction of the two mixed numbers.

Step 1: Convert the mixed numbers to improper fractions. -2 4/5 = -2 * 5/5 + 4/5 = -10/5 + 4/5 = -14/5 -7 2/9 = -7 * 9/9 + 2/9 = -63/9 + 2/9 = -61/9

Step 2: Rewrite the expression with the simplified fractions. -14/5 - (-61/9)

Step 3: To subtract fractions, we need a common denominator. The common denominator for 5 and 9 is 45. -14/5 * 9/9 - (-61/9 * 5/5) = -126/45 + 305/45

Step 4: Combine the fractions. = (-126 + 305)/45 = 179/45

The expression -2 4/5 - (-7 2/9) simplifies to 179/45.
