Question

(2.2+(-1/3)+(-3 1/15)

Answer 1

2 2/10-1/3-3 1/15= -1 6/30=-1 1/5

Answer 2

2 1/5-1/3-46/15=11/5-1/3-46/15=33/15-5/15-46/15= -1 1/5

Answer 3

To calculate the expression (2.2 + (-1/3) + (-3 1/15), we need to perform the addition and simplify the result.

First, let's convert the mixed number (-3 1/15) into an improper fraction:

-3 1/15 = -3 + 1/15

To add a whole number and a fraction, we need to find a common denominator. In this case, the common denominator is 15:

-3 + 1/15 = -45/15 + 1/15 = (-45 + 1)/15 = -44/15

Now, let's substitute the converted mixed number back into the expression and simplify:

2.2 + (-1/3) + (-3 1/15) = 2.2 + (-1/3) + (-44/15)

To add fractions, we need a common denominator. The common denominator in this case is 15:

2.2 + (-1/3) + (-44/15) = (33/15) + (-5/15) + (-44/15)

Now, let's add the fractions:

(33/15) + (-5/15) + (-44/15) = (33 - 5 - 44)/15 = (-16/15)

Therefore, the value of the expression (2.2 + (-1/3) + (-3 1/15) is -16/15.
