Question

1/3 X + 2 2/5 равно 3 и 2/3​

Answer 1

(1/3)х + 2 2/5 = 3 2/3

(1/3)х = 3 2/3 - 2 2/5

(1/3)х = 3 10/15 - 2 6/15

(1/3)х = 1 4/15

х = 1 4/15 : 1/3

х = 19/15 · 3/1

х = 19/5

х = 3 целых 4/5

--------------------------------

Проверка: 1/3 · 19/5 + 2 2/5 = 19/15 + 2 6/15 = 2 25/15 = 3 10/15 = 3 2/3

Answer 2

Ответ:

Пошаговое объяснение:

1/3 X + 2 2/5 = 3  2/3​

1\3х=3 2\3-2 2\5

1\3х=3 10\15-2 6\15

1\3х=1 4\15

х=1 4\15:1\3

х=19\15*3

х=19\5

х=3 4\5

Answer 3

To solve the equation 1/3 X + 2 2/5 = 3 2/3, we need to simplify the mixed numbers and fractions, then isolate the variable X.

First, let's convert the mixed numbers to improper fractions: 2 2/5 = (5 * 2 + 2)/5 = 12/5 3 2/3 = (3 * 3 + 2)/3 = 11/3

Now we can rewrite the equation: 1/3 X + 12/5 = 11/3

To eliminate the fractions, we can multiply the entire equation by the least common multiple (LCM) of the denominators of the fractions involved, which in this case is 3 * 5 = 15.

15 * (1/3 X) + 15 * (12/5) = 15 * (11/3) 5X + 36 = 55

Next, let's isolate the variable X by moving the constant term to the other side of the equation: 5X = 55 - 36 5X = 19

Finally, divide both sides of the equation by 5 to solve for X: X = 19/5

Therefore, the solution to the equation is X = 19/5 or 3 4/5.
