Question

1)-7/10+(-8/15)= 2)5/12+(-11/18)=

Answer 1

1) -7/10+(-8/15)= -(21/30+16/30)= -37/30= -1 7/30

2)5/12+(-11/18)=15/36-22/36= -(22/26-15/36)= -7/36

Answer 2

To solve these equations, we need to find the common denominator for each pair of fractions, then perform the addition. Let's solve them step by step:

1. (-7/10) + (-8/15):

The common denominator for 10 and 15 is 30.

(-7/10) can be written as (-21/30), and (-8/15) can be written as (-16/30).

Now we can add:

(-21/30) + (-16/30) = (-37/30)

Therefore, (-7/10) + (-8/15) = (-37/30).

2. (5/12) + (-11/18):

The common denominator for 12 and 18 is 36.

(5/12) can be written as (15/36), and (-11/18) can be written as (-22/36).

Now we can add:

(15/36) + (-22/36) = (-7/36)

Therefore, (5/12) + (-11/18) = (-7/36).
