Question

A=1/6 b=2/3 c=-5/8 / это дробная черта Задание:Найдите значение выражения (a+b)+c

Answer 1

a=1/6 b=2/3 c=-5/8

$(a+b)+c=(\frac{1}{6}+\frac{2}{3} )+(-\frac{5}{8} )=\frac{1+4}{6} -\frac{5}{8} =\\ \\ \frac{5*4-5*3}{24} =\frac{20-15}{24} =\frac{5}{24}$

Answer 2

To find the value of the expression (a + b) + c, we need to substitute the given values for a, b, and c and then perform the arithmetic operations.

Given values: a = 1/6 b = 2/3 c = -5/8

Now, let's perform the calculation step-by-step:

Step 1: Add a and b. (a + b) = (1/6) + (2/3)

Step 2: Find a common denominator for the fractions. The common denominator for 6 and 3 is 6.

Step 3: Convert the fractions to have the common denominator. (a + b) = (1/6) + (4/6)

Step 4: Add the fractions with the common denominator. (a + b) = (1 + 4)/6 (a + b) = 5/6

Step 5: Add c to the result from Step 4. (a + b) + c = (5/6) + (-5/8)

Step 6: Find a common denominator for 6 and 8, which is 24.

Step 7: Convert the fractions to have the common denominator. (a + b) + c = (20/24) + (-15/24)

Step 8: Add the fractions with the common denominator. (a + b) + c = (20 - 15)/24 (a + b) + c = 5/24

So, the value of the expression (a + b) + c is 5/24.
