Answer:

1) -3/4 + 2/9

=> -27+8/36

=> -19/36

2) 5/6 * -4/7

= -20/42

= - 10/ 21

3) -3/7

4) 27/2 + 54/3 + 61/4

LCM of 2,3,4 = 12

( 126 + 216 + 183 ) / 12

525 / 12

5)let x be the number to be added to 2/7 to get 5/4

then

2/7 + x = 5/4

x = 5/4 + 2/7. LCM of 4 and 7 = 28

=( 35 + 8 )/7

= 43 / 7
