Question

(-1/12- 3/4)+(-0,47-0,53) -1 1/8 =​

Answer 1

Ответ: - 2целых 23/24

Пошаговое объяснение:

1) - 1/12 - 3/4 = - 1/12 - 9/12 = - 10/12 = - 5/6

2) -0,47 - 0,53 = - 1

3) -5/6 + (-1)= -1целая 5/6

4) -1целая 5/6 - 1целая 1/8 = -1целая 20/24 - 1целая 3/24 = - 2целых 23/24

Answer 2

To simplify the given expression, let's perform the calculations step by step:

-1/12 - 3/4:

To add or subtract fractions, we need to have a common denominator. In this case, the common denominator is 12.

-1/12 - 3/4 = (-1/12) - (9/12) = -10/12 = -5/6.

Next, we'll simplify the decimal part:

-0.47 - 0.53 = -0.47 + (-0.53) = -0.47 - 0.53 = -1.00.

Now let's simplify the mixed number:

1 1/8 can be converted to an improper fraction by multiplying the whole number (1) by the denominator (8) and adding the numerator (1). The result is (8 + 1) / 8 = 9/8.

Finally, let's substitute the values into the expression and calculate:

(-5/6) + (-1.00) - (9/8) = -5/6 - 1 - 9/8.

To add or subtract fractions, we need a common denominator. The least common multiple (LCM) of 6 and 8 is 24.

(-5/6) + (-1.00) - (9/8) = (-20/24) - (24/24) - (27/24).

Now that we have a common denominator, we can combine the fractions:

= (-20 - 24 - 27) / 24.

= -71/24.

Therefore, the simplified value of the expression is -71/24.
