`(679)/(45)div(23)/(2130)xx(126)/(169)=?`

Evaluate: ((7)/(16)xx-(64)/(42))+((6)/(-45)xx(135)/(126))

The value of ((3)/(5) + (1)/(5)-(3)/(10)) xx ((36)/(45) div (16)/(5)) is

(18)/(126) xx 360

(800div64)xx(1296div36)=?

sqrt((324)/(49))xx sqrt((676)/(169))xx(126)/(sqrt(81))=x

From a well shuffled deck of cards, 2 cards are drawn with replacement. If x represent numbers of time ace coming, then the value of P(x=1)+P(x=2) is (a) (25)/(169) (b) (24)/(169) (c) (49)/(169) (d) (23)/(169)
