Question

Решить уравнение x=11 1/12-9 1/8

Answer 1

1)11 1/12 - х = 9 1/8

2)60 3/14 - х = 41 4/21

3)77 4/15 - х = 59 8/9

4)61 5/8 - х = 52 1/6

Answer 2

To solve the equation x = 11 1/12 - 9 1/8, we need to perform some arithmetic operations to simplify the expression and find the value of x.

Step 1: Convert the mixed numbers into improper fractions. 11 1/12 = (12 * 11 + 1) / 12 = 133 / 12 9 1/8 = (8 * 9 + 1) / 8 = 73 / 8

Step 2: Rewrite the equation with the improper fractions: x = 133 / 12 - 73 / 8

Step 3: Find a common denominator for the fractions, which is 24 (the least common multiple of 12 and 8). To convert 133/12 to an equivalent fraction with a denominator of 24: 133/12 * 2/2 = 266/24 To convert 73/8 to an equivalent fraction with a denominator of 24: 73/8 * 3/3 = 219/24

Step 4: Now, the equation becomes: x = 266/24 - 219/24

Step 5: Subtract the fractions: x = (266 - 219) / 24 x = 47 / 24

The solution to the equation is x = 47/24.
