Question

97,6:(9,4*30,5)*(4,22+1,08)-0,7*0,005:0,5*2800

Answer 1

488/5:286,7×5,3-19,6=
=488/5:2867/10×53/10-98/5=
=488/5+10/2867×53/10-98/5=
=8/5×1/47×53-98/5=
=424/235-98/5=
=-4182/235=
= - 17 187/235

Answer 2

To solve this expression, you should 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). Let's break down the expression step by step:

1. Start with the innermost parentheses:

   • Inside the first parentheses, you have 9.4 * 30.5, which equals 286.7.
   • Inside the second parentheses, you have 4.22 + 1.08, which equals 5.3.

2. Now, replace the expressions inside the parentheses with their results:

   • 97.6 / (286.7 * 5.3) - 0.7 * 0.005 / 0.5 * 2800

3. Perform the multiplications and divisions from left to right:

   • 97.6 / (286.7 * 5.3) simplifies to 97.6 / 1518.91.
   • 0.7 * 0.005 / 0.5 simplifies to 0.0035 / 0.5.

4. Continue with the divisions:

   • 97.6 / 1518.91 is approximately 0.0641 (rounded to four decimal places).
   • 0.0035 / 0.5 is equal to 0.007.

5. Now, subtract the two results:

   • 0.0641 - 0.007 is equal to approximately 0.0571 (rounded to four decimal places).

So, the final result of the expression is approximately 0.0571.
