Question

(5/6-1/3)+(1/2+9/10) help

Answer 1

Ответ:

1.9

Пошаговое объяснение:

5/6 - 1/3 = 5/6 - 2/6 = 3/6 =0.5

1/2 + 9/10 = 5/10 + 9/10 = 14/10 = 1.4

0.5 + 1.4 = 1.9

Answer 2

Вот сам ответ правильный 19/10

Answer 3

To simplify the expression (5/6 - 1/3) + (1/2 + 9/10), you can follow these steps:

Step 1: Simplify the fractions within the parentheses first.

For the first fraction (5/6 - 1/3), you need to find a common denominator. In this case, the common denominator is 6. Convert both fractions to have a denominator of 6:

5/6 - 1/3 = (5/6) - (2/6) = 3/6

For the second fraction (1/2 + 9/10), you need to find a common denominator. In this case, the common denominator is 10. Convert both fractions to have a denominator of 10:

1/2 + 9/10 = (5/10) + (9/10) = 14/10

Step 2: Combine the simplified fractions.

Now that you have 3/6 and 14/10, you can add them together. However, before doing so, it's advisable to simplify the fractions further by reducing them to their simplest form.

3/6 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 3:

3/6 = (3 ÷ 3) / (6 ÷ 3) = 1/2

14/10 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2:

14/10 = (14 ÷ 2) / (10 ÷ 2) = 7/5

Step 3: Add the simplified fractions.

Now that the fractions are simplified, you can add them together:

1/2 + 7/5 = (1 × 5 + 7 × 2) / (2 × 5) = (5 + 14) / 10 = 19/10

Therefore, the simplified expression is 19/10.
