Question

72/73х34/65+72/73*39/65=...?

Answer 1

1).

$\frac{72}{73} \times \frac{34}{65} = \frac{72 \times 34}{73 \times 65} = \frac{2448}{4745}$

2).

$\frac{72}{73} \times \frac{39}{65} = \frac{72}{73} \times \frac{3 \times 13}{5 \times 13} = \frac{72 \times 3}{73 \times 5} = \frac{216}{365}$

3).

$\frac{2448}{4745} + \frac{216}{365} = \frac{2448 + 13 \times 216}{4745} = 1 \frac{7}{65}$

Answer 2

Ответ:

Пошаговое объяснение:

= 72/73*(34/65 + 39/65) = 72/73 * 73/65 = 72/65 = 1 7/65

Answer 3

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 your expression step by step:

1. First, perform the multiplications and divisions from left to right: 72/73 * 34/65 = (72 * 34) / (73 * 65) 39/65 = 39/65

2. Now, perform the multiplications and divisions in the second part of the expression: 72/73 * 39/65 = (72 * 39) / (73 * 65)

3. Add the two results together: (72 * 34) / (73 * 65) + (72 * 39) / (73 * 65)

4. Now, combine the fractions by finding a common denominator (73 * 65): [(72 * 34) + (72 * 39)] / (73 * 65)

5. Factor out the common factor of 72 from the numerator: (72 * (34 + 39)) / (73 * 65)

6. Calculate the sum in the numerator: (72 * 73) / (73 * 65)

7. The "73" in the numerator and denominator cancels out: 72 / 65

So, the simplified result is 72/65.
