1) 1 1/12 - 2 5/8 2) (-1/6+2/3)-(3,74-5,89) СРОЧНОООООО ДАЮ 20 БАЛЛОВ

Answer 1

Вот надеюсь подчерк поймёшь

Answer 2

2)=(1/6+2/3)-(-2,15)=(1+2*2/6)+2,15=1/2+2,15=0,5+2,15=2,65
1)11/12-21/8=2*11-3*21/24=22-63/24=-41/24=-1 17/24

Answer 3

1. To subtract mixed numbers, we need to convert them into improper fractions first.

1 1/12 can be converted to an improper fraction as follows:

1 1/12 = (12*1 + 1)/12 = 13/12

Similarly, 2 5/8 can be converted to an improper fraction as:

2 5/8 = (8*2 + 5)/8 = 21/8

Now, we can subtract the fractions by finding a common denominator:

13/12 - 21/8 = (132)/(122) - 21/8 = 26/24 - 21/8

Next, we need to find a common denominator of 24 and 8, which is 24.

26/24 - 21/8 = 26/24 - (213)/(83) = 26/24 - 63/24

Finally, we can subtract the fractions with the same denominator:

26/24 - 63/24 = -37/24

Therefore, 1 1/12 - 2 5/8 = -37/24 or approximately -1.54.

2. (-1/6+2/3)-(3.74-5.89)

We can simplify the expression as follows:

-1/6 + 2/3 = 1/2

3.74 - 5.89 = -2.15

Now, we can substitute these values into the expression:

1/2 - (-2.15) = 1/2 + 2.15 = 2.65

Therefore, (-1/6+2/3)-(3.74-5.89) = 2.65.
