Here's the question:
Aisha’s first summer job
requires her to travel downtown. She is
interested in finding out how most
people get to work each day, so she finds
the results of an online survey.
According to the survey below, what
percent of the workers walk to work?
Ok here is the info about how to reach the answer:
Drive Alone- 7,862,918
Carpool- 1,120,982
Take public Transit-144,959
Walk- 138,496
Other means- 149,641
Work At Home- 346,626
I have no clue how to find the answer. Please help.
First, let's remember what "percent" means.
When you look at, say, 66% (I'm pretty sure that that's not the right answer, I just picked it), that means, out of 100 people, you have 66 of them.
Another way to look at percent is like a fraction. 66%=66/100
100 is the total, and 66 is the number of people who walk.
So, if percent is like a fraction, let's make a fraction.
How many people are there in total?
How many walk to work?
All right, that's the first step.
The second is to make a fraction.
We want the top to be the people we want (that is, the people who walk to work), and the bottom is everybody (that is, the total)
Then, once you have a fraction, you turn it into a decimal number.
An example: 7/20=.35
The last step is to multiply by 100.
7/20=.35=35%
And that is it!
