Jacquie found out that 40% of the 1,800 students in her school are going to the pep rally.

a) What percent are not going? -- 60%

now i need help and whut do you put on the calculator to find it?

b) how many students are not going to the rally?

c) what fraction ( in lowest terms ) will be at the pep rally?

d) what decimal shows the percent of students not attending?

a) 100 - (the percent going) = (the percent not going)

40 = (the percent going)

100 - 40 = (the percent not going)

the percent not going = 60

b) we know 60% of the students are not going to the rally...

so it is 60% of 1800

60% = 60/100 OR 3/5 OR .6

60% of 1800 also means 60% * 1800

3/5 * 1800

1170 students are not going to the rally

c) converting a percentage to a fraction is easy, just take the fraction and put it over 100

so 40% would become 40/100... that simplifies to 2/5

d) changing to a decimal is also easy... 60% means 60/100, which means .60 or .6
