Answer 2

To solve this expression, you can follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). In this case, there are no parentheses or exponents, so we'll perform the multiplication and division from left to right:

1. 425400:600 * 79:

   • First, perform the division: 425400 / 600 = 709.
   • Now, multiply the result by 79: 709 * 79 = 55,811.

2. 9100:70 - 2800:40:

   • First, perform the division: 9100 / 70 = 130.
   • Next, perform the division: 2800 / 40 = 70.
   • Finally, subtract the second result from the first: 130 - 70 = 60.

So, the final result is 60.
