SRVS STUDENT.

CLASS -8

Step-by-step explanation:

Dear student,

-2/3*5/6-2/3*4/7. (Multiply)

-10/18-8/21. (Take LCM of 18,21)

-210/378-144/378. (Subtract)

-354/378. (Simplify)

-118/126

-59/63.

OR

by using distributive property

= -2/3×5/6+(-2/3)×4/7

= -2/3×(5/6+4/7)

= -2/3×(35+24/42)

= -2/3×59/42

= -118/126

= -59/63
