Question

2целых 5\12-х=6 целых 7\8

Answer 1

2 5 - х = 6  7  
  12           8
-х = 6  7 - 2  5
          8     12
-х =  3/ 55 - 2/ 29
          8       12
-х =  165 - 58
           24 
-х =  7
     24
х =  - 7
     24  

Answer 2

To solve the equation, we'll convert the mixed numbers to improper fractions and perform the subtraction.

Let's convert the mixed numbers first: 2 whole and 5/12 can be written as an improper fraction: 2 * 12 + 5 = 24 + 5 = 29 So, 2 5/12 is equivalent to 29/12.

6 whole and 7/8 can be written as an improper fraction: 6 * 8 + 7 = 48 + 7 = 55 So, 6 7/8 is equivalent to 55/8.

Now we can subtract the fractions: 29/12 - 55/8

To subtract fractions, we need a common denominator. The least common multiple (LCM) of 12 and 8 is 24.

Converting the fractions to have a denominator of 24: (29/12) * (2/2) = 58/24 (55/8) * (3/3) = 165/24

Now we can subtract the fractions: 58/24 - 165/24 = (58 - 165)/24 = -107/24

The result of the equation 2 5/12 - x = 6 7/8 is -107/24.
