2,2+(-4 1/3) +(-1 13/15)

Answer 1

2,2+(-41/3)+(-113/15)=-19

Answer 2

To calculate the expression 2.2 + (-4 1/3) + (-1 13/15), we'll first convert the mixed numbers to improper fractions and then perform the addition:

Step 1: Convert mixed numbers to improper fractions. -4 1/3 can be converted to an improper fraction as follows: -4 1/3 = -(4 + 1/3) = -(4*3/3 + 1/3) = - (12/3 + 1/3) = - (13/3)

-1 13/15 can be converted to an improper fraction as follows: -1 13/15 = -(1 + 13/15) = -(1*15/15 + 13/15) = - (15/15 + 13/15) = - (28/15)

Step 2: Add the improper fractions. 2.2 + (-4 1/3) + (-1 13/15) = 2.2 + (-13/3) + (-28/15)

Step 3: Find a common denominator for the fractions, which is 15 (3*5). = 2.2 + (-65/15) + (-84/15)

Step 4: Add the fractions with the common denominator. = 2.2 + (-65/15 - 84/15)

Step 5: Combine the fractions. = 2.2 + (-149/15)

Step 6: Convert the mixed number to a decimal (if desired). = 2.2 - 9.9333... (approximately, as a decimal)

So, the final result is approximately -7.7333 when rounded to four decimal places.
