Answer:
4 - 5 = 40 books about travel. 80 are school stories.
6-7 = 30 are about nature. 48
8 =24
9 = 18
10 = 2001
Step-by-step explanation:
<h3>4,5,6,7,8</h3>
1/10 = 24 = sport
1/8 = 30 =nature
1/6= 40 =travel
1/5 = 48 = adventure
1/3 = 80 = schools stories
To get that you just have to read the question, find the fractions, percentages etc.
I put them all into fractions and divide 240 by the denominator.
<h3>9</h3>
For question 9, you just have to add all of the amounts of books together and take that away from the total amount. In this case it is 240 - 222 = 18
<h3>10</h3>
You just have to write it out.
