Answer 1

7300 is the answer for question

Answer 2

Answer:

7300 is the total number of books in the library

Step-by-step explanation:

long explanation:

we have 18 percent, but it would be easier to find 100 percent if we had 10 percent

18×5=90---> so if we multiply 18 % of the total into 5 you will get 90%

1314×5= 6570

now if we were to divide 90 by 9 we would get 10

90÷9= 10

which means if we divided 90% of the books by 9 you would get 10%

6570÷9= 730

now 10×10=100

so multiply 10% of the books into 10 to get 100 percent

730×10= 7300

short explanation:

1314×5 =6570----> 90%

6570÷9=730---->10%

730×10=7300---->100%

total number of books= 7300
