Answers
Answer:
3
Step-by-step explanation:
Looks like this is Percentage!
100% total
30% copies
60% books
10% registers
There are 30 items in total, which is 100%.
To calculate Copies :
Total Item × Item Percentage
Copies Percentage : 30%
Total Items : 30
Total Item × Item Percentage = 30 × 30%
= 9
Copies = 9
To calculate Books :
Total Item × Item Percentage
Books Percentage : 60%
Total Items : 30
Total Item × Item Percentage = 30 × 60%
= 18
Books = 18
To calculate Registers :
Total Item × Item Percentage
Registers Percentage : 10%
Total Items : 30
Total Item × Item Percentage = 30 × 10%
= 3
Registers = 3
To check your answers, add up the item counts ( in bold and underlined )
3 + 18 + 9 = 30
There is 9 copies, 18 Books and 3 Registers.
There are 3 registers in the bag.
