Question

please help me solve this. I'll mark the first person to answer CORRECTLY as brainliest​

Answer 1

different denominators so we want take L.C.M

D) L.C.M = 21

 -3 INTO 3 / -2 INTO 7 BY 21

= (+6) + (14)/21

= -20/21

H)

  7/6 MINUS 1/5

different denominators so we want take L.C.M

L.C.M = 30

7 INTO 5  / -1 INTO 5 BY 30

= 30 MINUS 5 BY 30

= 25/30

= 5/6

THESE ANSWERS ARE CAME IN MY MIND
