Question

4 3/ 7 ÷ 1 / 7 - 1 5/6 × 3=сроооооооочноооооо​

Answer 1

4 3/7 ÷ 1/7 - 1 5/6 × 3 = 31/7 ÷ 1/7 - 11/6 × 3 = 31/7 × 7 - 11/6 × 3 = 31 - 11/2 = 31 - 5,5 = 25,5

Answer 2

Ответ:

25,5

Пошаговое объяснение:

Представляем смешанные дроби в виде неправильных: 31/7 : 1/7 - 11/6 * 3

31/7 * 7 - 11/6 *3

Сокращаем 31/7 и 7 на 7: 31 - 11/6 * 3

Сокращаем 11/6 и 3 на 3: 31-11/2= 51/2= 25,5

Answer 3

Let's break down the expression step by step:

1. 4 3/7 ÷ 1/7 To divide a whole number by a fraction, you can multiply the whole number by the reciprocal of the fraction (flip the fraction and multiply).

   4 3/7 ÷ 1/7 = (4 + 3/7) × 7/1 = (31/7) × 7 = 31

2. 1 5/6 × 3 Multiply the mixed number by 3.

   1 5/6 × 3 = (1 + 5/6) × 3 = (11/6) × 3 = 11/2

Now, you have two simplified values:

• 4 3/7 ÷ 1/7 = 31
• 1 5/6 × 3 = 11/2

Now, let's perform the subtraction:

31 - 11/2

To subtract these two values, you need a common denominator:

31 - 11/2 = 62/2 - 11/2 = (62 - 11)/2 = 51/2

So, the final result is 51/2, which is the same as 25.5.
