As baseball fans enter the stadium, a free ball is given to every 21st spectator and a cap is given to every 27th spectator. Which spectator would be the first to receive both a ball and a cap?
Answered by Ms. Sue
21, 42, 63, 84, 105, 126, 147 . . .
Keep adding 21 to the previous number

27, 54, 81, 108, 135, 162 . . .
Keep adding 27 to the previous answer.

Stop when multiple of 21 and a multiple of 27 are the same.

Answered by edward
on a map an inch represents 200 miles how far is 3 1/4 inches?
Answered by Mbaintu
do 200*3.25 and that should probably give you the correct answer, which is 650.
