Answer 3

It looks like you've provided a mathematical expression that needs to be simplified. Let's break it down step by step:

Given expression: (13, 24 - 9 3/20) : 2 2/1 + (3/4 + 2 5/8) : 0/5

Step 1: Simplify the fractions and mixed numbers:

• 9 3/20 = 9 + 3/20 = 9 3/20
• 2 2/1 = 2 + 2 = 4
• 2 5/8 = 2 + 5/8 = 2 5/8
• 0/5 = 0 (any number divided by 0 is undefined)

Step 2: Substitute the simplified values back into the expression: (13, 24 - 9 3/20) : 4 + (3/4 + 2 5/8) : 0

Step 3: Perform the operations inside the parentheses:

• (13, 24 - 9 3/20) = 13, 24 - 9 3/20 = 13, 24 - 9.15 = 4, 9.85
• (3/4 + 2 5/8) = 3/4 + 2 5/8 = 3/4 + 21/8 = (6 + 21)/8 = 27/8

Substitute the results back into the expression: 4, 9.85 : 4 + 27/8 : 0

Step 4: Continue simplifying:

• 4 + 27/8 = (32 + 27)/8 = 59/8

Substitute the result back into the expression: 4, 9.85 : 59/8 : 0

Step 5: Convert the mixed number to a decimal: 4, 9.85 = 4 + 0.85 = 4.85

Substitute the result back into the expression: 4.85 : 59/8 : 0

Step 6: Convert the fraction to a decimal: 59/8 ≈ 7.375

Substitute the result back into the expression: 4.85 : 7.375 : 0

So, the simplified expression is: 4.85 : 7.375 : 0

Please note that the division by 0 in the original expression makes the expression undefined.
