2 4/7
1) Let's turn those mixed numbers into improper fractions, to make our calculations easier:
![\begin{gathered} 4(1)/(2)=(2*4+1)/(2)=(9)/(2) \\ 1(3)/(4)=(4*1+3)/(4)=(7)/(4) \\ \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/high-school/b21d23gk730o14y02qsaj06cl8a4k9kr3i.png)
2) Now let's divide those improper fractions, reciprocating the second one and multiplying it by the first one:
![(9)/(2)\colon(7)/(4)=(9)/(2)*(4)/(7)=(36)/(14)=(18)/(7)](https://img.qammunity.org/2023/formulas/mathematics/high-school/d8wg5ebvanqu2xwxbttf5f7nirzsktmg70.png)
3) Hence, we can write that the quotient of that division 4 1/2 by 1 3/4 is equal to 18/7. To turn it into a Mixed Number let's divide 18/7 and write our Mixed Number equivalent to 18/7:
