answer me fast plz​

Answer 1

Step-by-step explanation:

q1) 3/4 + (-5/6)

= 3/4 - 5/6. LCM of 4 and 6 is 12

so, (3/4×3/3) - (5/6×2/2)

= 9/12 - 10/12

= -1/12

q2) 2/3 × (-12/16)

= -1/2

Q3) 14/15 ÷28/25

= 14/15 × 25/28

= 5/6

q4) -3/2 - (-4/5)

= -3/2 + 4/5. LCM of 2 and 5 is 10

= (-3/2×5/5) + (4/5×2/2)

= -15/10 + 8/10

= -7/10

Answer 2

Step-by-step explanation:

the answer will be

1) 3/4-5/6=18-20/24=-2/24=-1/12

2) -24/32

3)14/15/28/25=14x25/15x28

4) -3/2+4/5

=-15+8/10=-7/10
