Question

1) |-2/5|+|3/10| 2) |2,65|+|-3.2| 20б

Answer 1

Ответ:

1) 7/10 (ну или удобнее 0,7)

2) 5,85

Пошаговое объяснение:

1) |-2/5|+|3/10| = 2/5 + 3/10 = 7/10

2) |2,65|+|-3,2| = 2,65 + 3,2 = 5,85

Answer 2

1. To simplify the expression |-2/5| + |3/10|, we evaluate the absolute values of -2/5 and 3/10 separately and then add them together.

|-2/5| = 2/5 |3/10| = 3/10

Now we can add them:

2/5 + 3/10

To add these fractions, we need a common denominator. The least common multiple of 5 and 10 is 10. Let's convert the fractions:

2/5 = 4/10 3/10 = 3/10

Now we can add them:

4/10 + 3/10 = 7/10

Therefore, |-2/5| + |3/10| equals 7/10.

2. To simplify the expression |2.65| + |-3.2|, we evaluate the absolute values of 2.65 and -3.2 separately and then add them together.

|2.65| = 2.65 |-3.2| = 3.2

Now we can add them:

2.65 + 3.2 = 5.85

Therefore, |2.65| + |-3.2| equals 5.85.
