Janet makes 50 snowballs and her brother makes 150 snowballs. What percentage of the snowballs did Janet make? Let's answer step by step:
First add the number of snowballs each person made to find the total: 50 snowballs + 150 snowballs = 200 snowballs. Then divide the number Janet made by the total number and multiply by 100% to express the answer as a percentage: 50 snowballs / 200 snowballs * 100% = 25%. The answer: 25.
