assistant
How many snowballs did Janet and her brother make? ** First add the number of snowballs each person made to find the total: 50 snowballs + 150 snowballs = <<50+150=200>>200 snowballs
What percentage of the snowballs did Janet make? ** 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%
