Answer 1

Answer:

a) 26/21

b) 23/9

c) (-41/78)

Step-by-step explanation:

a) subtraction of first number from second

2/3 - (-4/7) = 2/3 + 4/7

Taking LCM of 3 and 7

(14+12)/21

= 26/21

b) similarly as first part

5/9 - (-2)

taking LCM of 9 and 1

(5+18)/9

= 23/9

c) (-5/6) - (-4/13)

-5/6 + 4/13

taking LCM of 6 and 13

(-65+24)/78

= (-41/78)
