Answer 1

Пошаговое объяснение:

1) х+15/14=1*2/24

х= 1/12 - 15/14 = 7/84 - 90/84 = -83/84

2) 27/45-х=18/45-4/75

х = 27/45 - 18/45 + 4/75 = 9/45 +4/75 = 1/5 + 4 /75 = 15/75 + 4/75 = 19/75

3) 1-45/45= 1 - 1 = 0

4) 4/10+1= 1 2/5

5) 11/10-1= 11/10 - 10/10 = 1/10

Answer 2

Let's solve the equations step by step:

1. х + 15/14 = 1 * 2/242

To solve for х, first, we need to isolate х on one side of the equation. Start by subtracting 15/14 from both sides:

х = (1 * 2/242) - 15/14

Next, let's simplify the right-hand side:

х = 2/242 - 15/14

To add or subtract fractions, they need a common denominator. The common denominator here is 14 * 242 = 3388. So, let's rewrite the fractions with this common denominator:

х = (2 * 14)/(242 * 14) - (15 * 242)/(14 * 242)

х = 28/3388 - 3630/3388

Now, combine the fractions:

х = (28 - 3630)/3388

х = -3602/3388

Finally, simplify the fraction and check if there is a common factor:

х = -1801/1694

2. 27/45 - х = 18/45 - 4/75

To solve for х, let's first combine like terms on the right-hand side:

27/45 - х = (18 * 5)/(45 * 5) - (4 * 3)/(75 * 3)

27/45 - х = 90/225 - 12/225

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

27/45 - х = (90 - 12)/225

27/45 - х = 78/225

Next, we can simplify the fraction and check for a common factor:

27/45 - х = 2/5 - х = 2/25

Now, isolate х on one side:

х = 2/5 - 2/25

To add or subtract fractions, they need a common denominator. The common denominator here is 25. So, let's rewrite the fractions with this common denominator:

х = (2 * 5)/25 - 2/25

Now, combine the fractions:

х = (10 - 2)/25

х = 8/25

3. 1 - 45/45 = ?

The fraction 45/45 is equal to 1 (any number divided by itself is 1). Therefore:

1 - 45/45 = 1 - 1 = 0

4. 4/10 + 1 = ?

To add these two numbers, you first need to find a common denominator, which is 10 in this case. Then you can add the fractions:

4/10 + 1 = (4 + 10)/10 = 14/10

Now, simplify the fraction:

14/10 = 7/5

So, the result is 7/5.

5. 11/10 - 1 = ?

To subtract 1 from 11/10, we need a common denominator, which is 10. Then we can perform the subtraction:

11/10 - 1 = (11 - 10)/10 = 1/10

So, the result is 1/10.
