`2/7xx7/7-"4/3`

-7/3xx-7/3xx-7/3xx-7/3xx-7/3

Show that -4/3xx(2/5+(-7/10))=(-4/3xx2/5)+(-4/3xx(-7/10))

[2/7 + 4/7] xx [4'2/3] = "____"

(-4/7)^2xx(-7/2)^4

Simplified value of ((4/7)^5xx(-2/3)^4)/((4/9)xx(4/7)^3)

Simplify: (1/4xx2/7)-\ (5/(14)xx(-2)/3)+\ (3/7xx9/2)

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

3-(1)/(2)of(4)/(7)+(5)/(7)xx(14)/(35)=
