`5/7+(- 12)/5=- 12/5+5/7`

2. Verify the following: -12/7 + 2/5 = 2/5 + -12/7

Verify the following:- (ii) (-15)/(4)times((3)/(7)+(-12)/(5))=((-15)/(4)times(3)/(7))+((-15)/(4)times(-12)/(5)) .

5/9 - 7/12 + 1/2 =_

5/9+7/12+1/3

Write down the reciprocal of: (i) 5/8 (ii)7 (iii) 1/12 (iv) 12 3/5

Verify the following: (i) (-12)/(5)+(2)/(7)=(2)/(7)+(-12)/(5) (ii) (-5)/(8)+(-9)/(13)= (-9)/(13)+(-5)/(8) (iii) 3+(-7)/(12)=(-7)/(12)+3 (iv) (2)/(-7)+(12)/(-35)=(12)/(-35)+(2)/(-7)

Show that (12 !)/(5! 7!) + (12 !)/(6! 6!) = (13 !)/(6! 7!)

5/4-7/6-(-2)/3=\ 3/4 (b) -3/4 (-7)/(12) (d) 7/(12)
