To add these fractions, we first need to find a common denominator. The denominators of these fractions are 5, so we can use that as the common denominator.
So, -8 1/5 can be written as -40/5 + 1/5.
Similarly, 4 1/5 can be written as 20/5 + 1/5.
Adding the fractions together, we get:
(-40/5 + 1/5) + (20/5 + 1/5)
= -40/5 + 1/5 + 20/5 + 1/5
Combining the numerators, we get:
= (-40 + 1 + 20 + 1)/5
Simplifying the numerator, we get:
= (-40 + 20 + 1 + 1)/5
= (-19)/5
So, -8 1/5 + 4 1/5 is equal to -19/5.
Therefore, the answer is -19/5.

Add −8 1/5 + 4 1/5. (1 point)
To add -8 1/5 and 4 1/5, we add the whole numbers and the fractions separately.
The whole numbers -8 and 4 add up to -4.
Now, let's add the fractions 1/5 and 1/5. Since the fractions have the same denominator, we can add the numerators directly: 1 + 1 = 2.
Putting it all together, -8 1/5 + 4 1/5 is equal to -4 + 2/5.
Therefore, -8 1/5 + 4 1/5 adds up to -4 2/5.
The whole numbers -8 and 4 add up to -4.
Now, let's add the fractions 1/5 and 1/5. Since the fractions have the same denominator, we can add the numerators directly: 1 + 1 = 2.
Putting it all together, -8 1/5 + 4 1/5 is equal to -4 + 2/5.
Therefore, -8 1/5 + 4 1/5 adds up to -4 2/5.
Add −8 1/5+ 4/5. (1 point)
To add -8 1/5 and 4/5, we first need to convert the mixed number -8 1/5 to an improper fraction.
To convert -8 1/5 to an improper fraction, we multiply the whole number -8 by the denominator 5 and add the numerator 1. Then, we place the result over the denominator 5.
So, -8 1/5 becomes (-8 * 5 + 1)/5 = -41/5.
Now, we can add the fractions -41/5 and 4/5:
-41/5 + 4/5 = (-41 + 4)/5.
Simplifying the numerator, we have:
= -37/5.
Therefore, -8 1/5 + 4/5 is equal to -37/5.
To convert -8 1/5 to an improper fraction, we multiply the whole number -8 by the denominator 5 and add the numerator 1. Then, we place the result over the denominator 5.
So, -8 1/5 becomes (-8 * 5 + 1)/5 = -41/5.
Now, we can add the fractions -41/5 and 4/5:
-41/5 + 4/5 = (-41 + 4)/5.
Simplifying the numerator, we have:
= -37/5.
Therefore, -8 1/5 + 4/5 is equal to -37/5.
Add − 8/15 + 4/15. (1 point)
To add -8/15 and 4/15, we simply add the numerators and keep the common denominator of 15.
-8/15 + 4/15 = (-8 + 4)/15 = -4/15.
Therefore, -8/15 + 4/15 is equal to -4/15.
-8/15 + 4/15 = (-8 + 4)/15 = -4/15.
Therefore, -8/15 + 4/15 is equal to -4/15.
-1 3/10 + (-4 2/15)
To add -1 3/10 and -4 2/15, we first need to convert the mixed numbers to improper fractions.
-1 3/10 can be written as (-1 * 10 + 3)/10 = -13/10.
Similarly, -4 2/15 can be written as (-4 * 15 + 2)/15 = -58/15.
Now, we can add the fractions:
-13/10 + (-58/15).
To add fractions with different denominators, we need to find a common denominator. In this case, the least common multiple (LCM) of 10 and 15 is 30.
So, we need to rewrite the fractions with a common denominator of 30:
-13/10 = (-13 * 3)/ (10 * 3) = -39/30.
-58/15 = (-58 * 2)/ (15 * 2) = -116/30.
Now, we can add the fractions:
-39/30 + (-116/30) = (-39 + -116)/30 = -155/30.
The fraction -155/30 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 5:
-155/30 = (-31 * 5)/(6 * 5) = -31/6.
Therefore, -1 3/10 + (-4 2/15) is equal to -31/6.
-1 3/10 can be written as (-1 * 10 + 3)/10 = -13/10.
Similarly, -4 2/15 can be written as (-4 * 15 + 2)/15 = -58/15.
Now, we can add the fractions:
-13/10 + (-58/15).
To add fractions with different denominators, we need to find a common denominator. In this case, the least common multiple (LCM) of 10 and 15 is 30.
So, we need to rewrite the fractions with a common denominator of 30:
-13/10 = (-13 * 3)/ (10 * 3) = -39/30.
-58/15 = (-58 * 2)/ (15 * 2) = -116/30.
Now, we can add the fractions:
-39/30 + (-116/30) = (-39 + -116)/30 = -155/30.
The fraction -155/30 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 5:
-155/30 = (-31 * 5)/(6 * 5) = -31/6.
Therefore, -1 3/10 + (-4 2/15) is equal to -31/6.
-1.2 + 7.6
To add -1.2 and 7.6, we simply add the two numbers together:
-1.2 + 7.6 = 6.4.
Therefore, -1.2 + 7.6 is equal to 6.4.
-1.2 + 7.6 = 6.4.
Therefore, -1.2 + 7.6 is equal to 6.4.
-4.85 + 2.54
To add -4.85 and 2.54, we simply add the two numbers together:
-4.85 + 2.54 = -2.31.
Therefore, -4.85 + 2.54 is equal to -2.31.
-4.85 + 2.54 = -2.31.
Therefore, -4.85 + 2.54 is equal to -2.31.
4.6 + -9.04
To add 4.6 and -9.04, we simply add the two numbers together:
4.6 + (-9.04) = -4.44.
Therefore, 4.6 + -9.04 is equal to -4.44.
4.6 + (-9.04) = -4.44.
Therefore, 4.6 + -9.04 is equal to -4.44.
