Question

(18-10 целых 18\35)-(3 целых 9\28+2 целых 3\20=

Answer 1

(18 - 10 18/35) - (3 9/28 + 2 3/20) = 2 1/70.

Для решения данного примера сначала нужно выполнить действия в скобках, после этого выполнить вычитание.

Распишем пример по порядку выполнения действий в примере :

1) 18 - 10 18/35 = 18/1 - 368/35 = (18 * 35 - 368 * 1)/35 = 262/35 = 7 17/35;

2) 3 9/28 + 2 3/20 = 93/28 + 43/20 = (93 * 5 + 43 * 7)/140 = 766/140 = 383/70 = 5 33/70 ;

3) 262/35 - 383/70 = (262 * 2 - 383 * 1)/70 = 141/70 = 2 1/70.

Ответ : 2 1/70.

Answer 2

To solve the given expression, let's break it down step by step:

Step 1: Simplify each mixed fraction inside the parentheses.

First, simplify the fractions: 18/35 = 18 ÷ 35 = 0.5142857 (approximately) 9/28 = 9 ÷ 28 = 0.3214286 (approximately) 3/20 = 3 ÷ 20 = 0.15

Now, the mixed fractions: 3 whole and 9/28 = 3 + 9/28 = 3.3214286 (approximately) 2 whole and 3/20 = 2 + 3/20 = 2.15

Step 2: Perform the operations inside the parentheses.

(18 - 10) + (3.3214286 + 2.15)

Step 3: Simplify further.

8 + 5.4714286

Step 4: Calculate the final result.

8 + 5.4714286 ≈ 13.4714286

Therefore, the result of the expression is approximately 13.4714286.
