Answer: 36 are red
Step-by-step explanation:
3 out of every 5
5*12 = 60
so do 3*12 which = 36
36/60
100+ 100+ 100+ 9= 309
200+ 50 +50= 300
Petra has more stamps
Subtract to find the difference:
2000 - 500 = 1500
Divide the difference by the original population:
1500 / 500 = 3
Multiply that by 100 to get the percentage:
3 x 100 = 300%
