### Instruction:
Janet makes 50 snowballs and her brother makes 150 snowballs. What percentage of the snowballs did Janet make?

### Response:
First add the number of snowballs each person made to get a total of 50+150=<<50+150=200>>200 snowballs
Then divide the number Janet made by the total number and multiply by 100% to express the answer as a percentage: 50/200*100=<<50/200*100=25>>25%
