The proper way to write a large number in a sentence is: ten billion 10 billion 10,000,000,000 tens of billions the first option right?

The first two options are correct; Ten billion & 10 billion.

Explanation:

When we are writing we want it be as comprehensible as possible. Adding information that is hard to read can be distracting and the audience can lose interest.  For example take a look at the three sentences below:

Maria thinks that the world population is ten billion.

Maria thinks that the world population is 10 billion.

Maria thinks that the world population is 10,000,000,000.

The first two sentences are easily readable, but in the third sentence the reader starts counting zeroes, and therefore is distracted from the main subject and he may even decide to not pursue it further.

Therefore the first two are best options when writing a large number in a sentence.

there on the beach was a struggling turtle.   around its bright green neck was a loop of soda can rings.   in order to the planet, i have made a few changes to my life.   the first change is reducing the number of straws used. the second change was to recycle.   finally, i have worked hard to clean up litter.   it is important to clean our ocean.

you may not think straws have a large impact but they do.   imagine for every straw you sip out of a poor, , adorable turtle is being harmed.   one way i chipped in to is by using metal straws.   these straws are reusable and inexpensive.   another change is simply turning down straws.   by refusing a straw, i’m the turtles one drink at a time.  

however, the ocean just doesn't have turtles.   there are lots of creatures that live there and are harmed by all the litter.   to prevent litter from growing it’s important to recycle.   for me, i have started to buy most goods that are made out of recycled material.   pura vidas, chacos, purses, and too many other items to even count.   plus, when you buy those products they give money to charities.   not only am i the environment, but i’m also feeling better about my self.   finally, i have worked hard to clean up litter.   it is important to clean our ocean.
