Using the frequency table, find the percentage who have reading as a hobby. Give your answer rounded to the nearest integer.
We can see from the table that there were six students who had reading as a hobby. There were a total of 38 students. This means that six out of the 38 students had reading as a hobby.
We were asked to give our answer as a percentage. The word percent means out of 100. Therefore, to convert any fraction into a percentage, we need to multiply by 100. In this case, we need to multiply six 38ths by 100. Typing this into the calculator gives us an answer of 15.789 and so on.
We were asked in the question to round our answer to the nearest integer or whole number. This means that the deciding number is the seven in the tenths column. As this is greater than five, we need to round up. 15.789 rounded to the nearest integer is equal to 16. We can therefore say that 16 percent of the students had reading as a hobby.
We could repeat this process to find the percentage of students that had singing, drawing, acting, and music as a hobby. For example, the percentage of students that had singing as a hobby can be calculated by multiplying seven 38ths by 100 as there were seven students who had singing as a hobby. This is equal to 18 percent to the nearest integer.
