Question

Обчисли a-b-c+d якщо а=10 b =3 9/14 c=4 12/14 d=2 8/14

Answer 1

a-b-c+d если, а=10 b =3 9/14 c=4 12/14 d=2 8/14

Решение:

10-3 9/14-4 12/14+2 8/14＝10-8 8/14+2 8/14＝10-8+2＝4

Answer 2

To compute the value of a-b-c+d, we'll first convert all the numbers to improper fractions and then perform the arithmetic operation. An improper fraction is a fraction where the numerator is greater than or equal to the denominator.

Given: a = 10 (whole number, so it's already an improper fraction) b = 3 9/14 = (3 * 14 + 9) / 14 = 51 / 14 c = 4 12/14 = (4 * 14 + 12) / 14 = 64 / 14 d = 2 8/14 = (2 * 14 + 8) / 14 = 36 / 14

Now, let's calculate a-b-c+d:

a - b - c + d = 10 - (51/14) - (64/14) + (36/14)

To perform the subtraction and addition, we need a common denominator, which is 14 in this case:

a - b - c + d = 10 - (51/14) - (64/14) + (36/14) = 10 - (51 + 64 - 36) / 14 = 10 - (79) / 14 = (140 - 79) / 14 = 61 / 14

So, a - b - c + d = 61/14.
