1)127410:274=465

2)307200:480=640

3)1085:31=35

4)465+640-35=1 070

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 addition and subtraction from left to right:

1. 127410:274 + 307200:480 - 1085:31

Now, let's simplify each part step by step:

• 127410 ÷ 274 = 465.6934306569343 (rounded to 13 decimal places)
• 307200 ÷ 480 = 640
• 1085 ÷ 31 = 35

Now, we can perform the addition and subtraction:

465.6934306569343 + 640 - 35 ≈ 1070.6934306569343

So, the result is approximately 1070.6934306569343.
