Answer 1

Пошаговое объяснение:

$-(-\frac{4}{5} +\frac{7}{12} ):(-\frac{38}{49} )=\frac{13}{60} :(-\frac{38}{49} )=\frac{637}{2280}$

Answer 2

To solve this expression, you can follow these steps:

Step 1: Convert the mixed numbers to improper fractions.

• Convert -4_15 to an improper fraction: -4_15 = -(4 + 15/15) = -4_1 = -4.
• Convert 7_12 to an improper fraction: 7_12 = 7 + 12/12 = 7_1 = 7.
• Convert -38_49 to an improper fraction: -38_49 = -(38 + 49/49) = -38_1 = -38.

Step 2: Rewrite the expression with the improper fractions.

• (-4/1 + 7/1) / (-38/1)

Step 3: Perform the addition in the numerator.

• (-4/1 + 7/1) = (-4 + 7)/1 = 3/1 = 3.

Step 4: Simplify the expression.

• (3/1) / (-38/1) = 3/(-38).

So, the simplified result of the expression is 3/(-38).
