Question

(7целых 5/12 - 3 целых 1/6) * 2 целых 2//17

Answer 1

$(7 \frac{5}{12} - 3 \frac{1}{6} ) \times 2 \frac{2}{17} = 4 \frac{5 - 2}{12} \times 2 \frac{2}{17} = 4 \frac{3}{12} \times 2 \frac{2}{17} = 4 \frac{1}{4} \times 2 \frac{2}{17} = \frac{51}{12} \times \frac{36}{17} = 9$

Answer 2

Ответ:

4 13/17

Пошаговое объяснение:

(7 5/12 - 3 1/6)*2 2/17 = (4 5/12 - 2/12)* 2 2/17 = 4 3/12 * 2 2/17 = 4 1/4 * 2 2/17=

17/4 * 36/17 = 36/4 = 9

Answer 3

To solve the expression (7 5/12 - 3 1/6) * 2 2//17, we need to convert the mixed numbers into improper fractions and perform the arithmetic operations.

Step 1: Convert mixed numbers to improper fractions: 7 5/12 = (7 * 12 + 5) / 12 = 89/12 3 1/6 = (3 * 6 + 1) / 6 = 19/6 2 2//17 = (2 * 17 + 2) / 17 = 36/17

Step 2: Perform the subtraction and multiplication operations: (89/12 - 19/6) * 36/17

To subtract fractions, we need a common denominator. The least common multiple (LCM) of 12 and 6 is 12, so we'll convert both fractions:

(89/12 - 19/6) * 36/17 = (89/12 - 38/12) * 36/17 = 51/12 * 36/17

Now, we can multiply the fractions: (51/12) * (36/17) = (51 * 36) / (12 * 17) = 1836 / 204 = 459/51

Step 3: Simplify the result: To simplify the fraction 459/51, we find the greatest common divisor (GCD) of the numerator and denominator, which is 3: 459/51 = (459/3) / (51/3) = 153/17

Therefore, (7 5/12 - 3 1/6) * 2 2//17 is equal to 153/17.
