Answer:

Step-by-step explanation:

420 = 1/4 so 4/4 is 4 420s

420 x 4 = 1680

Answer:

There are 1680 tickets

Step-by-step explanation:

If 3/4 of the tickets are sold

1 - 3/4 of the tickets are unsold

4/4 -3/4 = 1/4

There are 1/4 of the tickets left

There are 420 tickets left

1/4 of the tickets = 420

Multiply each side by 4

4*1/4 tickets = 4*420

tickets = 1680

There are 1680 tickets
