" 4."2(3)/(5)times(7)/(13)

(1)/(5)times(11)/(13)+7(4)/(5)times(1)/(13)=

((-4)/(3))times(1)/(2)+((-4)/(3))times((-7)/(5))

Proved that (2)/(3)times[(-6)/(7)times(4)/(5)]=[(2)/(3)times(4)/(5)]times((-6)/(7))

(1(1)/(13)times2(3)/(5))-:(7(1)/(2)times3(1)/(10))-:(28)/(279)

Simplify : f. (13)/(7) + 4 (4)/(5) xx (3)/(4) div (7)/(15)

Find : a. 4 (5)/(13)- 3 (7)/(13) + 2 (8)/(13)

Verify the following: (i) ((3)/(4)+(-2)/(5))+(-7)/(10)=(3)/(4)+((-2)/(5)+(-7)/(10)) (ii) ((-7)/(11)+(2)/(-5))+(-13)/(22)=(-7)/(11)+((2)/(-5)+(-13)/(22)) (iii) -1+((-2)/(3)+(-3)/(4))=(-1+(-2)/(3))+(-3)/(4)

Find the reciprocal (multiplicative inverse) of : (i) (3)/(5)xx(2)/(3) (ii) (-8)/(3)xx(13)/(-7) (iii) (-3)/(5)xx(-1)/(13)

Verify that: (2)/(3)xx(-(4)/(5)+(-(3)/(7)))=(2)/(3)xx(-(4)/(5))+(2)/(3)xx(-(3)/(7))
