Question

If the cost of a notebook is rs 8.75 , then how many notebook can be purchased for 131.25

Answer 1

Answer:

15

Step-by-step explanation:

to find the answer ee need to divide.

dividing is repeated subtraction.

no. of books= x

cost of one book =8.75

cost of x books =131.25

no. of books =

cost of x books ÷ cost of one book

x=131.25÷8.75

(remove the (.) and place it back after we find the answer)

x=13125÷875

x=15

to keep the(.) back we subtract the number of decimal places of one number from the other.

here there are two decimal places in both so 2-2=0

so we do not need a decimal point

you could buy 15 books

Answer 2

Given,

cost of one notebook let say $C = 8.75 Rs$

To purchase 'n' number of books of cost 'C' we need $(C*n)$$Rs$. of money i.e

$1 book------ > (8.75*1)\\'n' books------ > (8.75*n)$

in question given total cost for 'n' books = $131.25Rs.$

Now, we need to find the number of books 'n' purchased for 131.25

∴$131.25 = (C*n)\\ \\131.25 = (8.75*n)\\ \\n = \frac{131.25}{8.75} \\ \\n = 15$

∴ Total number of books can be purchased for $131.25$ rupees are $15$
