Question

please give answer with full solution​

Answer 1

Step-by-step explanation:

1st case

5/6+ -4/5

= L.C.M of 6 and 5 =30

therefore,

5/6 + -4/5

= 25+(-24)

30

=25-24

30

= 1/30

2nd case

5/6 × -4/5

=5 × -4

6 5

= -20/30 = -2/3

now,

sum÷product

= 1/30 ÷ -2/3

= 1/30× -3/2. (additive inverse of -2/3= -3/2)

= -1/20
