Question

The 1,840 rock concert tickets sold were twice the amount of jazz concert tickets sold

Answer 1

just divide 1840 by 2 and the answer is 920

so 920 jazz tickets were sold

Answer 2

So there where two times the amount of rock tickets sold than the jazz concert. If that is it then you divide the 1840 by 2 getting 920, dividing 1÷2 you get zero remainder 1, 18÷2= 9, 4÷2= 2, and 0÷2= 0. 920. Hope i helped :)
