-(8/15)+(4/15)

To subtract these fractions, you need to have a common denominator. In this case, the common denominator is 15.

So, the expression becomes:

-(8/15) + (4/15)

Next, subtract the numerators while keeping the denominator the same:

=(-8 + 4)/15

=(-4)/15

Therefore, the answer is -4/15.

-1 3/10 + (-4 2/15)

To add these mixed numbers, you first need to convert them into improper fractions.

-1 3/10 = -(1 * 10 + 3)/10 = -13/10

-4 2/15 = -(4 * 15 + 2)/15 = -62/15

Now, you can add the fractions:

-13/10 + (-62/15)

To add these fractions, you need a common denominator, which is 30:

=(-13/10)(3/3) + (-62/15)(2/2)
=(-39/30) + (-124/30)

Next, add the numerators:

=(-39 - 124)/30
=-163/30

Therefore, the answer is -163/30.

Add −1 3/10 +(−4 2/15).(1 point)

d) −5 1/5

c) −5 13/30

b) −2 5/6

a) −5 1/6

To add -1 3/10 and -4 2/15, first convert the mixed numbers to improper fractions:

-1 3/10 = -(1 * 10 + 3)/10 = -13/10
-4 2/15 = -(4 * 15 + 2)/15 = -62/15

Now, add the fractions:

-13/10 + (-62/15)

To add these fractions, you need a common denominator, which is 30:

=(-13/10)(3/3) + (-62/15)(2/2)
=(-39/30) + (-124/30)

Next, add the numerators:

=(-39 - 124)/30 = -163/30

Therefore, the correct answer is c) -5 13/30.
