Answer 2

Ответ:

В первом получается 50, а во втором 9

Answer 3

1. To calculate the expression 50 * 1.25 * 0.1 * 8, you can follow the order of operations (parentheses, exponents, multiplication/division, addition/subtraction) to simplify the expression:

50 * 1.25 * 0.1 * 8 = (50 * 1.25) * 0.1 * 8

Calculating within the parentheses first: 50 * 1.25 = 62.5

Now substitute the result back into the expression: 62.5 * 0.1 * 8 = 6.25 * 8

Finally, perform the remaining multiplication: 6.25 * 8 = 50

Therefore, 50 * 1.25 * 0.1 * 8 equals 50.

2. To calculate the expression 0.75 * 6.33 + 3.67 * 0.75 + 1.5, you can again follow the order of operations:

0.75 * 6.33 + 3.67 * 0.75 + 1.5

Performing the multiplications first: 0.75 * 6.33 = 4.7475 3.67 * 0.75 = 2.7525

Substituting the results back into the expression: 4.7475 + 2.7525 + 1.5

Finally, perform the additions: 4.7475 + 2.7525 + 1.5 = 9

Therefore, 0.75 * 6.33 + 3.67 * 0.75 + 1.5 equals 9.
