emily read 24 fiction books and 2 nonfiction books. what is the ratio of the number of fiction books she read to the total numbe
Elis [28]

Answer:

24:26 or 12:13

Step-by-step explanation:

Ratios can be better understood if you read 24:26 as: Emily read 24 fiction books for every 26 books.

The question tells us Emily read 24 fiction books and 2 nonfiction books. We know she read 24 fiction books so that is the first part of our ratio. Now, they want to know how many total books did she read. Well, she read 24 fiction and 2 nonfiction. 24+2 = 26. 26 books total! So now we have the second part of our ratio and end up with the ratio of 24:26. But now, we have to simplify it. Simplifying ratios is like simplyfing fractions. You have to find their greatest common factor. The greatest common factor of 24 and 26 is 2. Now you divide both number by their greatest common factor (2). Finally, we end up with the ratio of 12:13.

Joshua spends 25 minutes of each day reading.Let d be the number of days that he reads and let m represent the total minutes of
snow_tiger [21]
The independent variable is the days he spends reading because nothing we have can determine that. However the dependent variable is the total minutes of reading because it relies on the independent variable to figure out. You can't find the total minutes without knowing the days he spends. The equation sould be d times the amount he reads per day =m
