Answer 2

To solve the given expressions, we need to perform the operations step by step. Let's start with the first expression:

1 4/5 : (-4/5)

Step 1: Convert mixed numbers to improper fractions: 1 4/5 = (5*1 + 4)/5 = 9/5

Step 2: Division of fractions is the same as multiplying by the reciprocal, so we'll flip the second fraction and change the division to multiplication: 9/5 * (-5/4)

Step 3: Perform the multiplication: (9 * -5) / (5 * 4) = -45/20

Step 4: Reduce the fraction to the simplest form (if possible): -45/20 = -9/4

Now let's move on to the second expression:

-4/9 : (-1 1/9)

Step 1: Convert mixed numbers to improper fractions: -1 1/9 = (9 * -1 + 1)/9 = -10/9

Step 2: Division of fractions is the same as multiplying by the reciprocal, so we'll flip the second fraction and change the division to multiplication: -4/9 * (-9/10)

Step 3: Perform the multiplication: (-4 * -9) / (9 * 10) = 36/90

Step 4: Reduce the fraction to the simplest form (if possible): 36/90 = 2/5

So the solutions to the given expressions are:

1 4/5 : (-4/5) = -9/4 -4/9 : (-1 1/9) = 2/5
