Question

1\3 + ( 10,66 : 2 3\5 + 1 1\5 - 0,3) : 3

Answer 1

По действиям:
1) 10,66 : 23/5 = 49,036
2) 49,036 + 11/5 = 49,036 + 2,2 = 51,236
3) 51,236 - 0,3 = 50,936
4) 50,936 : 3 = 16,97866666666667
5) 1/3 + 16,97866666666667 = 17,312
Ответ: 17,312

Answer 2

Let's simplify the expression step by step, following the order of operations:

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

   10.66 ÷ 2 3/5 + 1 1/5 - 0.3 = 10.66 ÷ (2 + 3/5) + 1 1/5 - 0.3 (converting the mixed number to an improper fraction) = 10.66 ÷ (12/5) + 6/5 - 0.3 (converting the mixed number to an improper fraction) = 10.66 × 5/12 + 6/5 - 0.3 (dividing by a fraction is the same as multiplying by its reciprocal) = 4.4417 + 1.2 - 0.3 (approximating to 4 decimal places) = 5.3417

2. Now, let's simplify the expression outside the parentheses:

   1/3 + 5.3417 ÷ 3 = 1/3 + 1.7806 (dividing by a number is the same as multiplying by its reciprocal) = 1.1136

Therefore, the final result is 1.1136.
