Question

(х+11/12)-14/15=1целых3/10 решить уровнение

Answer 1

X+11/12=13/10+14/15
x=13/10+14/15-11/12
x=78/60+56/60-55/60
x= 79/60= 1 19/60

Answer 2

(х + 11/12) - 14/15 = 1 3/10,
х + 11/12 - 14/15 = 1 3/10,
х = 1 3/10 - 11/12 + 14/15,
х = 13/10 - 11/12 + 14/15,
х = 78/60 - 55/60 + 56/60,
х = 79/60,
х = 1 19/60

Answer 3

To solve the equation (х + 11/12) - 14/15 = 1 целых 3/10, we need to find the value of х that satisfies the equation.

Step 1: Convert the mixed number 1 целых 3/10 to an improper fraction. 1 целых = 1 (the whole number part) 3/10 = 1 + 3/10 (the fraction part) 1 целых 3/10 = 1 + 3/10 = 10/10 + 3/10 = 13/10

So, the equation becomes: (х + 11/12) - 14/15 = 13/10

Step 2: Find a common denominator for the fractions on the left-hand side of the equation. The common denominator for 12 and 15 is 60.

Step 3: Rewrite the equation with the common denominator (60): 60 * (х + 11/12) - 60 * 14/15 = 60 * 13/10

Step 4: Simplify the equation: 60х + 55 - 56 = 39

Step 5: Combine the constants: 60х - 1 = 39

Step 6: Isolate the variable х: 60х = 39 + 1 60х = 40

Step 7: Solve for х by dividing both sides by 60: х = 40 / 60

Step 8: Simplify the fraction: х = 2/3

So the solution to the equation is х = 2/3.
