b. is a mixed fraction
please help me​

Answer 1

Answer:

a) (-7/8)+(8/9)

First take the LCM of 8 and 9 to make the denominators same

After we have taken LCM we got:-

(-63/72)+(64/72)

-1/72

B) 3(3/7)+(-5/14)

Multiplying 3 by 3/7 Its 9/7 so now we have

9/7+(-5/14)

(+)(-) is (-)

so, 9/7-5/14

Taking LCM of 7and 14 its 14

Now we have

18/14-5/14

Now denominators are same we can subtract them. After subtracting we got

13/14

Answer 2

Answer:

(-63+64)/72 =1/72

2) 6-5/14= 1/14
