    =(9 x 90)/(10 x 90)-(8 x 90)/(9 x 90)


    step 5 Simplify the expression to have common denominator:
    =81/90-80/90


    step 6 Take the common values out and rewrite the above expression like the below:
    =1/90 x (81/1-80/1)
    =1/90 x (81 - 80)


    step 7Simplify the above expression further:
    =1/90 x 1
    =1/90
    9/10-8/9=1/90
