To work this out we need to calculate the percentage of boys in year 10 and year 11. Then we can compare them to find which year has the greater proportion of boys.For Year 10 there are 110 boys out of 200 students so we find the fraction and multiply it by 100 to get a percentage, shown below:(110/200)*100=55%For Year 11 there are 140 boys out of 250 students so we do the same as above and then compare the values, shown below:(140/250)*100=56%therefore there is a higher proportion of boys in year 11 as 56%>55%.
