Question

A store donated 4 ½ dozen cookies for a fundraiser. Another store donated 3 ¼ dozen cookies. How many dozen cookies did they donate altogether?

Answer 1

the number of dozen cookies donated altogether is
`7(3)/(4)`

Explanation:

Given that

The store donated 4 1 ÷ 2 dozen cookies

And, the another store donated 3 1 ÷ 4 dozen cookies

we need to find oyt the no of dozen cookies donated altogether is

`= 4 (1)/(2) + 3 (1)/(4) \\\\= (9)/(2) + (13)/(4) \\\\= (18 + 13)/(4) \\\\= (31)/(4)\\\\= 7(3)/(4)`

Hence, the number of dozen cookies donated altogether is
`7(3)/(4)`
