Answer 2

Let's break down the calculations step by step:

1. Subtracting Fractions: First, we'll subtract the fractions 19/20 and 4/5:

   19/20 - 4/5

   To subtract fractions, they need to have a common denominator. The common denominator here is 20, which is the least common multiple of 20 and 5.

   Convert both fractions to have the same denominator:

   19/20 = 19/20 4/5 = 16/20

   Now subtract:

   19/20 - 16/20 = 3/20

2. Adding Fractions: Next, we'll add the fractions 8/11 and 33/40:

   8/11 + 33/40

   To add fractions, they also need a common denominator. The common denominator here is 440, which is the least common multiple of 11 and 40.

   Convert both fractions to have the same denominator:

   8/11 = 320/440 33/40 = 363/440

   Now add:

   320/440 + 363/440 = 683/440

So, the results are:

• 19/20 - 4/5 = 3/20
• 8/11 + 33/40 = 683/440
