He shared the remaining pieces of cookies equally among his 5 friends. 5-.3 a) Show the above information in a mathematical expression using brackets. 5) Simplify the expression and find how many pieces of cookies did each friend get?​

Answer 1

each friend will get 3 pieces of cookie.

Explanation:

Let's represent the given information in a mathematical expression using brackets:

Total number of cookies = 2 packets * 12 cookies/packet = 24 cookies

Pratik ate 4 cookies, so the remaining number of cookies is:

Remaining cookies = Total number of cookies - Cookies eaten by Pratik

Remaining cookies = 24 cookies - 4 cookies = 20 cookies

Pratik gave 5 cookies to his brother, so the remaining number of cookies is:

Remaining cookies = Remaining cookies - Cookies given to Pranav

Remaining cookies = 20 cookies - 5 cookies = 15 cookies

Now, Pratik wants to share the remaining pieces of cookies equally among his 5 friends. To find out how many pieces of cookie each friend gets, we need to divide the remaining number of cookies by the number of friends:

Number of pieces of cookie each friend gets = Remaining cookies / Number of friends

Number of pieces of cookie each friend gets = 15 cookies / 5 friends = 3 cookies per friend

Therefore, each friend will get 3 pieces of cookie.
