To add -8/15 and 4/15, we simply combine the numerators and keep the same denominator:
-8/15 + 4/15 = (-8 + 4)/15 = -4/15
Therefore, the sum is -4/15.

add – 1 3/10 + (– 4 2/15).
To add -1 3/10 and -4 2/15, we first have to convert the mixed numbers to improper fractions.
-1 3/10 = -10/10 + 3/10 = -13/10
-4 2/15 = -60/15 + 2/15 = -58/15
Now we can add the fractions:
-13/10 + (-58/15)
To add these fractions, we need a common denominator, which is 30:
-13/10 = -39/30
-58/15 = -116/30
Now we can add the fractions:
-39/30 + (-116/30) = -155/30
Since -155/30 cannot be simplified any further, the sum is -155/30.
-1 3/10 = -10/10 + 3/10 = -13/10
-4 2/15 = -60/15 + 2/15 = -58/15
Now we can add the fractions:
-13/10 + (-58/15)
To add these fractions, we need a common denominator, which is 30:
-13/10 = -39/30
-58/15 = -116/30
Now we can add the fractions:
-39/30 + (-116/30) = -155/30
Since -155/30 cannot be simplified any further, the sum is -155/30.
add -1 3/10 + (-4 2/15) (1 point)
To add -1 3/10 and -4 2/15, we'll first convert the mixed numbers into improper fractions.
-1 3/10 = -(1*10 + 3)/10 = -13/10
-4 2/15 = -(4*15 + 2)/15 = -62/15
Now we can add the fractions:
-13/10 + (-62/15)
To add these fractions, we need a common denominator, which is 30:
-13/10 = -39/30
-62/15 = -124/30
Now we can add the fractions:
-39/30 + (-124/30) = -163/30
Therefore, -1 3/10 + (-4 2/15) equals -163/30.
-1 3/10 = -(1*10 + 3)/10 = -13/10
-4 2/15 = -(4*15 + 2)/15 = -62/15
Now we can add the fractions:
-13/10 + (-62/15)
To add these fractions, we need a common denominator, which is 30:
-13/10 = -39/30
-62/15 = -124/30
Now we can add the fractions:
-39/30 + (-124/30) = -163/30
Therefore, -1 3/10 + (-4 2/15) equals -163/30.

To sum -1 3/10 and -4 2/15, we'll first convert the mixed numbers into improper fractions.
-1 3/10 = -(1*10 + 3)/10 = -13/10
-4 2/15 = -(4*15 + 2)/15 = -62/15
Now we can add the fractions:
-13/10 + (-62/15)
To add these fractions, we need a common denominator, which is 30:
-13/10 = -39/30
-62/15 = -124/30
Now we can add the fractions:
-39/30 + (-124/30) = -163/30
Therefore, -1 3/10 + (-4 2/15) equals -163/30.
To simplify the fraction -163/30, we can write it as a mixed number:
-163/30 = -5 13/30
Therefore, the sum is -5 13/30.
The correct answer is option 3) -5 13/30.
-1 3/10 = -(1*10 + 3)/10 = -13/10
-4 2/15 = -(4*15 + 2)/15 = -62/15
Now we can add the fractions:
-13/10 + (-62/15)
To add these fractions, we need a common denominator, which is 30:
-13/10 = -39/30
-62/15 = -124/30
Now we can add the fractions:
-39/30 + (-124/30) = -163/30
Therefore, -1 3/10 + (-4 2/15) equals -163/30.
To simplify the fraction -163/30, we can write it as a mixed number:
-163/30 = -5 13/30
Therefore, the sum is -5 13/30.
The correct answer is option 3) -5 13/30.
add -1.2 + 7.6.
To add -1.2 and 7.6, we simply sum the numbers:
-1.2 + 7.6 = 6.4
Therefore, the sum is 6.4.
-1.2 + 7.6 = 6.4
Therefore, the sum is 6.4.
add -4.85 + (-2.54).
To add -4.85 and -2.54, we simply sum the numbers:
-4.85 + (-2.54) = -7.39
Therefore, the sum is -7.39.
-4.85 + (-2.54) = -7.39
Therefore, the sum is -7.39.
add 4.6 + (-9.04)
To add 4.6 and -9.04, we simply sum the numbers:
4.6 + (-9.04) = -4.44
