The pie chart below shows how we, as a nation, commute to work. Change each percent to a fraction in lowest terms.
How We Commute
Car pool
11%
Drive alone
80%
Public transit
5%
Other
4%

Explanation:

We divide the percentage values over 100 as you have done so for the first two boxes.

Drive alone = 80/100 = 4/5

Car pool = 11/100

For the remaining two boxes, we do the same thing.

Public transit = 5/100 = 1/20

Other = 4/100 = 1/25

To reduce the fraction 5/100, we divide both parts by the GCF 5

So that's how 5/100 turns into 1/20

The same idea applies to 4/100 turning into 1/25 (except the GCF is 4 this time).

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
