Question

8 biscuits cost 24p altogether. How much do 5 cost

Answer 1

15p should be your answer

Explanation:

Well, 8 biscuits cost 24p all together, and 24/8=3 so 1 biscuit is 3p.

So now 3*5= 15 so 5 biscuits is 15p

Answer 2

In the question the cost of 8 biscuits is already given. Based on that the price of 5 biscuits can be easily deduced.
The cost of 8 biscuits = 24 p
Cost of 1 biscuit = (24/8) p
= 3p
Then
The cost of 5 biscuits = (3 * 5) p
= 15p
Hence the cost of 5 biscuits is 15p. I hope the procedure for finding the correct answer is clear to you. If you closely follow the method of doing this problem, then in future you can do it by yourself.
