Question

Eric surveyed 40 students at his school and found that 0.65 of the students he surveyed said their favorite class is math. Another 35% of the students he surveyed reported that their favorite class is science. How many more students in the survey prefer math over science?

Answer 1

Answer:

12 students

Step-by-step explanation:

So we know that 65% of students prefer math over the 35% of students that prefer science.

To find the answer we have to change the percentages to decimals and multiply by 40, which is the total number of students.

Math: 65%=0.65 , so 0.65 times 40=26 students

Science:35%=0.35, so 0.35 times 40=14 students

To find the difference, subtract 26 and 14, to get 12.

All in all, twelve students prefer math over science.

Hope I helped, have a nice day :)

Answer 2

Answer:

Answer is 12 more students prefer math over science.

Step-by-step explanation:

For this question all you need to to is multiply the decimal or the percent by 40 to get the student ratio. So for the math. 40 * .65 = 26. So 26 students like math.

For the science we do 40*35% or if you want to write it decimal form 40*.35 = 14. Okay now we have both values all you need to do to get the difference is subtact 26-14= 12. 12 more students prefer math over science.
