Question

- 2 1/6+(-0,9)+3 1/15

Answer 1

-1/3-0,9+1/5

-1/3-9/10+1/5

-31/30

Answer 2

To solve the expression, let's first convert all the mixed numbers to improper fractions and then perform the addition:

1. Convert mixed numbers to improper fractions:

   • 2 1/6 = (2 * 6 + 1) / 6 = 13 / 6
   • 3 1/15 = (3 * 15 + 1) / 15 = 46 / 15

2. Rewrite the expression with improper fractions: 13/6 + (-0.9) + 46/15

3. Find a common denominator, which is the least common multiple (LCM) of 6 and 15, which is 30.

4. Rewrite the fractions with the common denominator: (13/6) * (5/5) + (-0.9) * (30/30) + (46/15) * (2/2) (65/30) - 27/30 + 92/30

5. Add the fractions with the same denominator: (65 - 27 + 92) / 30 130 / 30

6. Simplify the fraction (if possible): 130 / 30 = 13 / 3

So, the result of the expression is 13/3.
