For #1:
look at the chart and write the percentages that are by the name of the food and write the percentages next to the names
For #2:
take the percentage number and divide it by 2 (because it was 50 customers out of 100%) for example if 50% of the customers picked apples then divide it by 2 and 25 customers would have gotten apples and put that number next to the name
Hope that helps :D
