Question

Пожалуйста помогите!!! 1) -2 3/4 - (-1 3/16) 2) -3 11/12 - 4 3/8 3) 4,82 - 12,038 4) 12,3 - x = 3,08 5) -6,2 + x = -9,32 Умоляю помогите!!!!

Answer 1

Пошаговое объяснение:

1) -2 3/4 - (-1 3/16)

-11/4+1 3/16

-11/4+19/16

-25/16

2) -3 11/12 - 4 3/8

-(3 11/12+4 3/8)

-((3+4)+(11/12+3/8))

-(7+31/24)

-(7+1+7/24)

-(8+7/24)

-8 7/24

3)4,82 - 12,038

-(12,038-4,82)

-7,218

4)12,3 - x = 3,08

-x=3,08-12,3

-x=-9,22

5) -6,2 + x = -9,32

x=-9, 32+6,2

x=-3,12

Answer 2

1) -2 + 3/4 - (-1 + 3/16)

To solve this expression, we can follow the order of operations (PEMDAS/BODMAS). Let's break it down step by step:

-2 + 3/4 - (-1 + 3/16)

First, let's simplify the expression inside the parentheses:

-2 + 3/4 - (-1 + 3/16) -2 + 3/4 - (-16/16 + 3/16) -2 + 3/4 - (-13/16)

Next, let's simplify the subtraction inside the parentheses:

-2 + 3/4 - (-13/16) -2 + 3/4 + 13/16

Now, let's find a common denominator for the fractions:

-2 + 3/4 + 13/16 -2 + (3/4 * 4/4) + 13/16 -2 + 12/16 + 13/16

Finally, let's add the fractions:

-2 + 12/16 + 13/16 -2 + 25/16

To simplify the expression further, we can convert the mixed number -2 to an improper fraction:

-2 = -2/1

Now, let's add the fractions:

-2/1 + 25/16

To add fractions, we need to find a common denominator:

-2/1 * 16/16 = -32/16 25/16

Now, let's add the fractions:

-32/16 + 25/16 = -7/16

Therefore, the value of -2 + 3/4 - (-1 + 3/16) is -7/16.
