Explanation:

2.) 3/8

3.) 3/8

4.) Couldn't read this one, too blurry

5.) 5/12

6.) 3/10

7.) 5/12

8.) 1/8

9.) 1/5

10.) 1/8

11.) 1/4

Step-by-step explanation:

So the thing about subtracting fractions is that you have to have the same denominator for both of them. (that's the number on the bottom.) So number 3 is 7/8 - 1/2. You're gonna wanna multiply 1/2 by four, for both the top and bottom number. This creates 4/8. Now you can subtract them! 7-4 = 3, and thus the answer is 3/8. You never, ever subtract the denominator: only the numerator.

-4h + 13  

Step-by-step explanation:

(5h + 7) - ( 9h -6)  is the same  as (5h -9h)  ( 7 + 6)

solve for each

5h - 9h = -4h

7+ 6 = 13

-4h + 13

1.) This is a really broad questions... one way to stop wasting water is to take shorter showers.
2.) Educate children more about why wasting water is bad. A lot of people understand this, but they don't know why.
3.) Less than 1% of the worlds water is freshwater..
4.) Because millions of people don't have water available to them.
5.) Used water can be used to water your plants, grass, or something else.
6.) People don't know the reason why wasting water is bad, they just know that wasting water is bad.
7.) People waste water by running their sink, while doing something or flushing the toilet multiple times. There are also a lot of leaks which add up to hundreds of gallons over the year.
8.) Overuse of freshwater in household means there is less fresh water for agricultural use and the demand for water is rising exponentially with the increase of our population. 
9.)  A lot
10.) The demand for water is getting higher with the increase of our population.
11.) Isn't this the same as number 5?...

1)Put plastic bottles in your toilet tank - Put an inch of sand or pebbles inside each of two plastic bottles, fill them with water, and put them in your toilet tank, safely away from operating mechanisms. The bottles may displace and save 10 or more gallons of water a day.
2)Shorten your showers by 1 or 2 minutes.Water your plants in the evening when it is dark, so the water won't evaporate.Wash your laundry 2 times a week.Make sure to keep a jug of water in the refrigerator.Collect rain water.Always turn the water off when you brush your teeth.
3)There are anthropocentric, biocentric, and ecocentric reasons why wasting water is bad. Anthropocentrically, fresh water is a vital resource for the survival of our population. ... Therefore, wasting water in a country where it may appear water just magically comes out of the tap.
4)Therefore, wasting water in a country where it may appear water just magically comes out of the tap.
5)Go Native. Use native plants in your landscape. ...Reduce Chemical Use. Use fewer chemicals around your home and yard, and make sure to dispose of them properly - don't dump them on the ground!Manage Waste. ...Don't Let It Run. ...Fix the Drip. ...Wash Smarter. ...Water Wisely. ...Reduce, Reuse, and Recycle.
6)But flood irrigation wastes tons of water and can pollute waterways with ... less waster runoff, and covering crops to prevent water evaporation.
7)From lawns to flood irrigation, here are five ways that people waste water and some ways to reduce that waste. Irrigation. Agriculture uses about 70 percent of the available freshwater on the planet. Lawns. Poor crop choice. Newer plants. Flushed down the toilet.
8)Furthermore, in places where clean water is scarce, overusing or wasting household water limits the availability of it for other communities to use for drinking, cleaning, cooking or growing—and thus contributes to disease, illness, or agricultural scarcity/starvation.
9)Wasted water comes with a cost. The city of Daytona Beach, Fla., estimates that a faucet leaking 10 drips every minute wastes 526 gallons of water per year, adding up to $10.91. Clearly, a running toilet can waste much more — and cost much more — than that.
10)Already, more than 2 billion people face a water scarcity each month, but tremendous amounts of water are still wasted.
11)Check your house for leaks. ...Turn off the faucet when you brush your teeth. ...Water your yard in the morning or evening. ...Take a shorter shower. ...Never use the toilet as a trash can.
