Answer:
the number of dozen cookies donated altogether is [tex]7\frac{3}{4}[/tex]
Step-by-step 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
[tex]= 4 \frac{1}{2} + 3 \frac{1}{4} \\\\= \frac{9}{2} + \frac{13}{4} \\\\= \frac{18 + 13}{4} \\\\= \frac{31}{4}\\\\= 7\frac{3}{4}[/tex]
Hence, the number of dozen cookies donated altogether is [tex]7\frac{3}{4}[/tex]
