Mrs lane took a survey of the types of pants her students were wearing. She collected the data of the types of pants her students were wearing, what percent of her students were wearing shorts? 10 were wearing jeans, 9 were wearing shorts and 2 were wearing capris.

Answers

It is always important to go through the given problem first to get a concept of the requiremement. Then all the information's available from the question has to be noted down in such a manner that there would be no need to look at the question while solving.
Total number of students wearing jeans = 10
Total number of students wearing shorts = 9
Total number of students wearing capris = 2
Then the total number of students surveyed by Mrs Lane = (10 + 9 + 2)
= 21
Now percentage of students wearing shorts = (9/21) * 100
   = (3/7) * 100
   = 300/7
   = 42.85 percent
So a total percentage of 42.85% of the students were wearing shorts.

What number does 584 round to? 580 or 585?

Answers

Rounding to the nearest 5, it rounds to 585. This is because it is closer to 585 than 580. However, rounding to the nearest 10, it rounds to 580.

580
You can remember this by saying
5 or more let it soar
4 or less let it rest
Which means if there's 5 or more round up but if it's 4 or less round it down
