вот, держи, надеюсь привильно ты условие написал и я решила

Answer 2

To solve the expression 3 1/6 + (2 5/9) - (-1 7/12), we need to convert the mixed numbers into improper fractions.

Let's start by converting the mixed numbers:

3 1/6 = (6 * 3 + 1) / 6 = 19/6 2 5/9 = (9 * 2 + 5) / 9 = 23/9 -1 7/12 = (12 * -1 + 7) / 12 = -5/12

Now we can substitute these values into the expression:

19/6 + 23/9 - (-5/12)

To add fractions, we need to find a common denominator. In this case, the least common multiple (LCM) of 6, 9, and 12 is 36.

Converting the fractions to have a denominator of 36:

(19/6) * (6/6) = 114/36 (23/9) * (4/4) = 92/36 (-5/12) * (3/3) = -15/36

Now we can rewrite the expression:

114/36 + 92/36 - (-15/36)

To subtract a negative number, we can change it to addition:

114/36 + 92/36 + 15/36

Now we can add the fractions:

(114 + 92 + 15) / 36 = 221/36

Therefore, 3 1/6 + (2 5/9) - (-1 7/12) equals 221/36.
