Question

-1,14*(-2,5) -4 1/12 : (-1 1/6)

Answer 1

-1,14*(-2,5)= 1,14*2,5=2,85

Answer 2

To simplify the expression, follow these steps:

1. Convert all mixed numbers to improper fractions.
2. Perform the multiplications and divisions from left to right.

Let's break it down step by step:

1. Convert mixed numbers to improper fractions:

   -2.5 = -5/2 -1 1/6 = -7/6

2. Rewrite the expression with the improper fractions:

   -1,14 * (-5/2) - (4 1/12) / (-7/6)

Now, let's calculate:

-1,14 * (-5/2) = -7 * (-5/2) = 35/2

(4 1/12) / (-7/6) = (49/12) / (-7/6)

To divide fractions, multiply by the reciprocal of the divisor:

(49/12) * (-6/7) = -294/84

Now, we can simplify further:

35/2 - (-294/84)

To add or subtract fractions, they need a common denominator. In this case, the common denominator is 84.

35/2 = (35 * 42) / (2 * 42) = 1470/84

Now, subtract:

1470/84 - (-294/84) = 1470/84 + 294/84

Now, add the fractions:

(1470 + 294)/84 = 1764/84

Finally, simplify the fraction:

1764/84 = 21

So, the result of the expression is 21.
