(13)/(25)times 1 (7)/(8)

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

Show ((-8)/(7))times[(1)/(2)times((-4)/(3))]=[((-8)/(7))times(1)/(2)]times((-4)/(3))

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

(7)/(8)times((17)/(13)+(14)/(13))=((7)/(8)times(14)/(13))+((7)/(8)times .....)

(1)/(1times3)+(1)/(3times5)+(1)/(5times7)+(1)/(7times9)+(1)/(9times11)+(1)/(11times13)

Let's simplify : frac(13)(25) xx 1frac(7)(8)

2 3/5-:5/7=\ (13)/7 (b) (13)/(25) (91)/(25) (d) (25)/(91)
