Question

А-б-с+д,якщо а=10,д=3 9/14,с=4 13/14,д=2 8/14 очень надо !!!

Answer 1

Ответ:

10-3 9/14-4 13/14 + 2 8/14= 4

Пошаговое объяснение:

1) 10 - 3 9/14 = 9 14/14 - 3 9/14 = 6 5/14 (берём 1 у 10 целых и получаеться 9 14/14 (неправельная дробь))

2) 6 5/14 - 4 13/14 = 5 19/14 - 4 13/14= 1 6/14 (большое от меньшего не вычетаеться, поэтому берём 1 у целых и добавляем 14 к числителю, и теперь можна вычетать)

3) 1 6/14 + 2 8/14= 3 14/14 = 4 (если числитель и знаменатель равны, то это не правельная дробы которая превращаеться в 1 которую мы добавляем до целых)

Удачи тебе :)

Calculation of Variables

To calculate the values of variables a, b, c, and d, we can use the given equations:

a = 10 d = 3 + 9/14 c = 4 + 13/14 d = 2 + 8/14

Let's calculate the values of b, c, and d:

b = a + c - d

Substituting the given values:

b = 10 + (4 + 13/14) - (2 + 8/14)

To simplify the calculation, let's convert the mixed fractions to improper fractions:

b = 10 + (4 + 13/14) - (2 + 8/14) = 10 + (4 * 14 + 13) / 14 - (2 * 14 + 8) / 14 = 10 + (56 + 13) / 14 - (28 + 8) / 14 = 10 + 69 / 14 - 36 / 14 = 10 + 69/14 - 36/14 = 10 + (69 - 36) / 14 = 10 + 33 / 14 = 10 + 2 5/14 = 10 + 2 + 5/14 = 12 + 5/14

So, the value of b is 12 5/14.

Now, let's calculate the value of d:

d = 3 + 9/14

Converting the mixed fraction to an improper fraction:

d = 3 + 9/14 = 3 * 14/14 + 9/14 = 42/14 + 9/14 = (42 + 9) / 14 = 51/14

So, the value of d is 51/14.

Finally, let's calculate the value of c:

c = 4 + 13/14

Converting the mixed fraction to an improper fraction:

c = 4 + 13/14 = 4 * 14/14 + 13/14 = 56/14 + 13/14 = (56 + 13) / 14 = 69/14

So, the value of c is 69/14.

To summarize: - a = 10 - b = 12 5/14 - c = 69/14 - d = 51/14

Please note that the calculations are based on the given equations and the assumption that the variables are independent of each other.
