Answer:
1260 books
Step-by-step explanation:
2/5=0.4
19000*0.4=7600
12500*0.4=5000
7600+5000=12600
1/10=0.1
12600*0.1=1260
A fraction is a way to describe a part of a whole. The number of books that are due back this week is 1,260.
A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
Given that 2/5 of the fiction books are checked out, and the total number of fiction books is 12,500. Therefore, the number of fiction books that are checked out is
[tex]\text{Number of fiction books that are checked out}= \dfrac25 \times (\text{Number of fiction books})\\\\\text{Number of fiction books that are checked out}= \dfrac25 \times 12,500 = 5,000[/tex]
Given that 2/5 of the non-fiction books are checked out, and the total number of non-fiction books is 19,000. Therefore, the number of non-fiction books that are checked out is
[tex]\text{Number of non-fiction books that are checked out} = \dfrac25 \times (\text{Number of non-fiction books})\\\\\text{Number of non-fiction books that are checked out}= \dfrac25 \times 19,000= 7,600[/tex]
Now, the total number of books that are due back this week,
[tex]\text{Total number of books that are due back this week} = \dfrac1{10} \times (\text{Total number of checked out books})[/tex]
[tex]\text{Total number of books that are due back this week} = \dfrac1{10} \times (5,000+7,600)\\\\\text{Total number of books that are due back this week} = 1,260[/tex]
Hence, the number of books that are due back this week is 1,260.
