Question

Will someone explain this to me step by step

Answer 1

Good evening

Explanation:

`(8)/(11)-(1)/(2) = (8*2)/(11*2)-(1*11)/(2*11) =(16)/(22)-(11)/(22) =(5)/(22)\\\\(1)/(10)+(2)/(5) = (1)/(10)+(2*2)/(5*2) =(1)/(10)+(4)/(10) =(5)/(10)\\\\(8)/(9)-(3)/(4) = (8*4)/(9*4)-(3*9)/(4*9) =(32)/(36)-(27)/(36) =(5)/(36)`
