Answer 2

Calculations

To solve the given expressions, let's start with the first one:

Expression 1: (3/4 + 1/20) × 1/2

First, let's simplify the terms inside the parentheses: 3/4 + 1/20 = 15/20 + 1/20 = 16/20 = 4/5

Now, we can proceed with the multiplication: 4/5 × 1/2 = 4/10 = 2/5

So, the result of the first expression is 2/5.

Now, let's move on to the second expression:

Expression 2: (7,3/5 - 2,4/15) × 9/32

First, let's convert the mixed numbers to improper fractions: 7,3/5 = 38/5 2,4/15 = 34/15

Now, we can perform the subtraction: 38/5 - 34/15 = (114/15 - 34/15) = 80/15 = 16/3

Finally, we can proceed with the multiplication: 16/3 × 9/32 = (16/3) × (9/32) = 144/96 = 3/2

So, the result of the second expression is 3/2.

Therefore, the solutions to the given expressions are: - (3/4 + 1/20) × 1/2 = 2/5 - (7,3/5 - 2,4/15) × 9/32 = 3/2
