The LCD of 11/20 and 31/45 is 180
20 40 60 80 100 120 140 160 180
45 90 135 180
A would be you answer I don't know to explain it though Plz place me as brainliest.
Half of the people bought tickets at $1.50, $1.50 times 15 equals $22.50
The other half bought them at the regular price of $2.75, $2.75 times 15 equals $41.25
When we combine the two money totals, we end up with a grand total of $63.75
the answer is 1.5 over 24. 1.5/24
