-(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.
