Question

1)x+4/5=9/10 2)x+1 1/12=1 1/83)51/100+x=9/50​

Answer 1

Ответ:

1) х = 1/10

2) х = 1/24

3) х = -33/100

Пошаговое объяснение:

1)x+4/5=9/10

х = 9/10 - 4/5

х = 9/10 - 8/10     х = 1/10

2)x+1 1/12=1 1/8

х = 1 1/8 - 1 1/12

х = 1 3/24 - 1 2/24     х = 1/24

3)51/100+x=9/50​

х = 9/50 - 51/100

х = 18/100 - 51/100    х = -33/100

Answer 2

To solve the equations, let's go through each one step by step:

1. x + 4/5 = 9/10

To get rid of the fraction, we can multiply both sides of the equation by the common denominator, which is 10:

10(x + 4/5) = 10(9/10)

10x + 8 = 9

Now, subtract 8 from both sides:

10x = 9 - 8

10x = 1

Finally, divide both sides by 10 to solve for x:

x = 1/10

So the solution to the first equation is x = 1/10.

2. x + 1 1/12 = 1 1/8

First, let's convert the mixed numbers to improper fractions:

x + 13/12 = 9/8

Next, we need to find a common denominator, which is 24:

24(x + 13/12) = 24(9/8)

24x + 26 = 27

Subtract 26 from both sides:

24x = 27 - 26

24x = 1

Divide both sides by 24 to solve for x:

x = 1/24

So the solution to the second equation is x = 1/24.

3. 51/100 + x = 9/50

Let's first get rid of the fractions by multiplying both sides by 100 to eliminate the denominators:

100(51/100 + x) = 100(9/50)

51 + 100x = 18

Now, subtract 51 from both sides:

100x = 18 - 51

100x = -33

Divide both sides by 100 to solve for x:

x = -33/100

So the solution to the third equation is x = -33/100.
