Question

0.6•(21.8+25.6)+0.7•(21.03-15.451)-32.2453​

Answer 1

0.6 (21.8 + 25.6) + 0×7 (21.03 - 15.451) - 32.2453 = -38053/10000

Answer 2

To calculate the expression:

0.6 * (21.8 + 25.6) + 0.7 * (21.03 - 15.451) - 32.2453

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).

Let's break it down step by step:

1. Inside the first set of parentheses: 21.8 + 25.6 = 47.4

2. Inside the second set of parentheses: 21.03 - 15.451 = 5.579

3. Multiply the results of the two sets of parentheses: 0.6 * 47.4 = 28.44 0.7 * 5.579 = 3.9053

4. Subtract the last number from the first two: 28.44 + 3.9053 - 32.2453 = 0.099

So, the result of the expression is approximately 0.099.
