Question

(1/2-0,375): 1/8 - (3 5/6-3 7/12) : (0,358 - 0,108)

Answer 1

очень надеюсь, что правильно :)

Answer 2

Let's break down the expression step by step:

1. First, simplify the fractions: (1/2 - 0.375) = (0.5 - 0.375) = 0.125

2. Next, subtract the mixed numbers within the parentheses: (3 5/6 - 3 7/12)

   First, convert both mixed numbers to improper fractions: 3 5/6 = (3 * 6 + 5)/6 = (18 + 5)/6 = 23/6 3 7/12 = (3 * 12 + 7)/12 = (36 + 7)/12 = 43/12

   Now, subtract: (23/6 - 43/12)

   To subtract fractions, you need a common denominator, which in this case is 12: (23/6) - (43/12) = (2 * 23/12) - (43/12) = (46/12) - (43/12) = (46 - 43)/12 = 3/12

3. Simplify the expression within the second set of parentheses: (0.358 - 0.108) = 0.25

4. Now, divide the result from step 3 by the result from step 2, and then divide the result by 1/8: (0.125) / (3/12) = (0.125) / (1/4) = 0.125 * 4 = 0.5

So, the final result of the expression is 0.5.
