Simplify : ((-3)/2xx4/5)+(9/5xx(-10)/3)-(1/2xx3/4)

Simplify: ((-16)/5xx(20)/8)-((15)/5xx(-35)/5) ((-3)/2xx4/5)+(9/5xx(-10)/3)-((1xx3)/(2xx4))

(5/9)^(-2) xx (9/5)^(-3) xx (9/10)^0

(4/9)^(-2) xx (4/9)^9 xx (4/9)^(-10)

1/2xx 5/4 + 6/8 xx 10/9

Simplify : [ ((- 3 )/( 2) xx (4)/(5) ) + ((9)/(5) xx (-10)/( 3)) - ((1)/(2)xx (3)/(4)) ] div [ ((21)/( 9) xx (3)/(7)) +((7)/(8) xx (16)/(14)) ]
