Answer 1

Ответ:

(5,625*1 1/3-3 11/18:5/9):1 2/3=3/5 или 0,6

Пошаговое объяснение:

5,625*1 1/3=7 1/2

3 11/18:5/9=6 1/2

7 1/2-6 1/2=1

1:1 2/3=3/5 или 0,6

Answer 2

To solve this expression, 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).

Your expression is:

(5,625 * 1 1/3 - 3 11/18 ÷ 5/9) ÷ 1 2/3

First, simplify the terms within parentheses:

1. 1 1/3 as an improper fraction is 4/3. So, 5,625 * 4/3 is 7,500.

2. 3 11/18 as an improper fraction is 59/18. Now, divide this by 5/9. To divide fractions, you can multiply by the reciprocal of the second fraction. So, 59/18 ÷ 5/9 becomes (59/18) * (9/5) = (59/18) * (9/5) = 531/90.

So, the expression becomes:

(7,500 - 531/90) ÷ 1 2/3

Now, subtract 531/90 from 7,500:

7,500 - 531/90 = 7,500 - 5.9 = 7,494.1

Finally, divide this result by 1 2/3:

To divide by a mixed number, convert it to an improper fraction first. 1 2/3 as an improper fraction is 5/3. So, the final calculation is:

7,494.1 ÷ 5/3

To divide by a fraction, multiply by its reciprocal:

7,494.1 * 3/5 = 4,496.46

So, the result of the expression is approximately 4,496.46.
