Question

5/12+(1-х)при х=2/3

Answer 1

Пошаговое объяснение:

5/12+(1-2/3)=5/12+1/3=3/4 или 0,75

Answer 2

To evaluate the expression 5/12 + (1 - x), where x = 2/3, we substitute the value of x into the expression and perform the calculations:

5/12 + (1 - (2/3))

First, let's simplify the expression inside the parentheses:

1 - (2/3) = (3/3) - (2/3) = 1/3

Now we can substitute this result back into the original expression:

5/12 + (1/3)

To add these fractions, we need to find a common denominator. The least common multiple of 12 and 3 is 12. So we can rewrite the fractions with a denominator of 12:

(5/12) + (1/3) = (5/12) + (4/12)

Now we can add the numerators:

5/12 + 4/12 = 9/12

The resulting fraction can be simplified by dividing the numerator and denominator by their greatest common divisor, which is 3:

(9/3) / (12/3) = 3/4

Therefore, the value of the expression 5/12 + (1 - x) when x = 2/3 is 3/4.
