Question

1 1/12+(-4/7)+(-5/12)+3/7= СРОЧНО

Answer 1

1 1/12 - 4/7 + -5/12 + 3/7 = (1 1/12 - 5/12) + (3/7 - 4/7) = 8/12 - 1/7 = 2/3 - 1/7 = 14/21 - 3/21 = 11/21

Answer 2

To solve the expression 1 1/12 + (-4/7) + (-5/12) + 3/7, we need to find a common denominator for the fractions involved. The common denominator for 12 and 7 is 84. Let's proceed with the calculations:

1 1/12 = (12/12) + (1/12) = 13/12 -5/12 remains as it is. -4/7 remains as it is. 3/7 remains as it is.

Now, let's substitute the fractions with their equivalent fractions with a common denominator:

(13/12) + (-4/7) + (-5/12) + (3/7) = (13/12) + (-28/84) + (-35/84) + (36/84)

Next, we can add the fractions together:

(13/12) + (-28/84) + (-35/84) + (36/84) = (109/84) - (63/84)

Subtracting the fractions:

(109/84) - (63/84) = 46/84

To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 2:

46/84 = (46 ÷ 2) / (84 ÷ 2) = 23/42

Therefore, the result of the expression 1 1/12 + (-4/7) + (-5/12) + 3/7 is 23/42.
