Question

{4- 3/10 - 1/5 } *10Хелп​

Answer 1

Ответ:

{4 - 3/10 - 1/5} * 10

Спершу виконаємо операції в дужках:

4 - 3/10 - 1/5 = 40/10 - 3/10 - 2/10

Тепер додамо числа з однаковими знаменниками:

(40/10 - 3/10 - 2/10) = (40 - 3 - 2) / 10 = 35/10

Тепер помножимо результат на 10:

(35/10) * 10 = (35 * 10) / 10 = 350/10

За потреби можна скоротити дріб:

350/10 = 35

Отже, вираз {4 - 3/10 - 1/5} * 10 дорівнює 35.

Answer 2

To simplify the expression {4 - 3/10 - 1/5} * 10, follow these steps:

1. First, simplify the expression inside the curly braces:

   {4 - 3/10 - 1/5}

2. Find a common denominator for the fractions in the expression. The common denominator for 10 and 5 is 10.

   {4 - (3/10) - (2/10)}

3. Subtract the fractions with the common denominator:

   {4 - (3/10 - 2/10)}

4. Simplify the fractions inside the braces:

   {4 - 1/10}

5. Now, subtract 1/10 from 4:

   4 - 1/10 = (40/10) - (1/10) = 39/10

6. Finally, multiply the result by 10:

   (39/10) * 10 = 39

So, the simplified expression is 39.
