Answer:
The fraction of the children in the group that contains both dog and a cat is [tex]\frac{17}{12}[/tex]
Step-by-step explanation:
The fraction of the children in the group that contains both dog and a cat is presented below:
= Pet dog + cat
[tex]= \frac{2}{3} + \frac{3}{4}\\\\= \frac{8 + 9}{12} \\\\= \frac{17}{12}[/tex]
Hence, the fraction of the children in the group that contains both dog and a cat is [tex]\frac{17}{12}[/tex]
