Question

4целых7/12-1целая5/12+2целых11/12​

Answer 1

Пошаговое объяснение:

$4 \frac{7}{12} - 1 \frac{5}{12} + 2 \frac{11}{12} = 6 \frac{1}{12}$

$1)4 \frac{7}{12} - 1 \frac{5}{12} = \frac{55}{12} - \frac{17}{12} = \frac{55 - 17}{12}$

$= \frac{38}{12} = \frac{19 \times 2}{6 \times 2} = 3 \frac{1}{6}$

$2)3 \frac{1}{6} + 2 \frac{11}{12} = \frac{19}{6} + \frac{35}{12} = \frac{2 \times 19 + 35}{12} = \frac{73}{12} = 6 \frac{1}{12}$

Answer 2

To solve this expression, we need to perform addition and subtraction of mixed numbers. Here's how we can proceed:

Step 1: Convert the mixed numbers into improper fractions.

4 7/12 = (4 * 12 + 7) / 12 = 55/12 1 5/12 = (1 * 12 + 5) / 12 = 17/12 2 11/12 = (2 * 12 + 11) / 12 = 35/12

Step 2: Perform the arithmetic operation.

55/12 - 17/12 + 35/12 = (55 - 17 + 35) / 12 = 73/12

Step 3: Simplify the result if necessary.

73/12 cannot be simplified further because the numerator and denominator do not have any common factors other than 1.

Therefore, the result is 73/12.
