Question

(1 10/25+6/1)×2 10/4​

Answer 1

Ответ:

33 3/10

Пошаговое объяснение:

Делаем по действиям.

1 10/25 + 6/1 = 1 10/25 + 6 = 7 10/25

Можно сократить до 7 2/5

Чтобы произвести умножение, следует привести все в неправильные дроби.

7 2/5 = 37/5

2 10/4 = 18/4

37/5 * 18/4= 666/20 = 33 6/20 = 33 3/10

Проверяем на калькуляторе.

7 2/5 = 7,4

18/4 = 4,5

7,4 * 4,5 = 33,(3)

Все верно.

Answer 2

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

1. Add the fractions within the parentheses:

   10/25 + 6/1 = 10/25 + 150/25 = (10 + 150)/25 = 160/25

2. Simplify the fraction:

   160/25 = 32/5

3. Now, multiply the result by 2 10/4:

   32/5 × 2 10/4

First, convert the mixed number 2 10/4 into an improper fraction:

2 10/4 = (2 × 4 + 10)/4 = 18/4

Now, multiply the fractions:

(32/5) × (18/4) = (32 × 18)/(5 × 4) = 576/20

Simplify the fraction:

576/20 = 144/5

So, the final result of the expression is 144/5.
