Answer 2

To solve the expression, let's break it down step by step:

Step 1: Evaluate the expressions inside parentheses

1. Evaluate the expression inside the first parentheses: -9 + 2 1/3.

   • Convert the mixed number 2 1/3 to an improper fraction: (2*3 + 1)/3 = 7/3.
   • Now the expression becomes -9 + 7/3.
   • To add these fractions, find a common denominator, which is 3 in this case.
   • Rewrite -9 as -27/3 to have the same denominator: -27/3 + 7/3 = -20/3.

2. Evaluate the expression inside the second parentheses: 16 * 12.5 + 1 13 30.

   • Convert the mixed number 1 13 30 to an improper fraction: (16060 + 13*60 + 30)/60 = (3600 + 780 + 30)/60 = 4410/60 = 147/2.
   • Now the expression becomes 16 * 12.5 + 147/2.
   • Multiply 16 by 12.5: 200.
   • Rewrite 200 as a fraction: 200/1.
   • The expression becomes 200/1 + 147/2.

Step 2: Perform the division

• Divide the expression obtained from Step 1 by the expression to the left of the division sign.
• The expression is: (200/1 + 147/2) / (-0.23).

Step 3: Evaluate the remaining multiplication and subtraction

• Multiply 0.005 by 1050: 0.005 * 1050 = 5.25.
• Subtract the result obtained from Step 2 by the multiplication result: (200/1 + 147/2) / (-0.23) - 5.25.

Step 4: Evaluate the final division

• Divide the expression obtained from Step 3 by -0.23: ((200/1 + 147/2) / (-0.23) - 5.25) / -0.23.

Now you can calculate the final result using a calculator or by performing the operations manually.
