Answer:
4 hours
Step-by-step explanation:
She will take 4 hours.
If she reads at 25 pages per 30 minutes, that will be 50 pages per hour.
It will take 2 hours to read 100 pages, therefore it will take 4 hours to read 200 pages.
Ok, so I'll make an example problem to show.
There's a forest in town and it's recorded that there are 5 bears and 100 squirrels in it.
First, you would make this a ratio so that would be 5:100. 5 being the bears and 100 being the squirrels.
To simplify it, just make it into a fraction. The first number, going from left to right, would be the numerator and 100 would be the denominator.
5
-----
100
To simplify, just divide by the greatest common factor which would be 5 in this case.
5 1
----- / 5 = ----
100 20
4/6, 6/9, 8/12, 10/15, 12/18, 14/21, 16/24, 18/27, etc.<span />
