Sagot :
[tex]\begin{gathered} 1)\frac{2}{3} \\ 2)6 \\ 3)\frac{5}{27} \\ 4)22 \\ 5)11 \end{gathered}[/tex]
1) We can find the quotient between two fractions by multiplying the first one by the reciprocal of the second one this way:
[tex]\frac{\frac{1}{2}}{\frac{3}{4}}=\frac{1}{2}\times\frac{4}{3}=\frac{4}{6}=\frac{2}{3}[/tex]2) Let's now divide 4 by 2/3 following the same principle:
[tex]\frac{4}{\frac{2}{3}}=4\times\frac{3}{2}=\frac{12}{2}=6[/tex]Notice that we have simplified as well as the previous item (1).
3) Proceeding with that we have:
[tex]\frac{\frac{5}{9}}{3}=\frac{5}{9}\times\frac{1}{3}=\frac{5}{27}[/tex]4) To find this out, we need to convert that Mixed Number to Improper Fraction:
[tex]\begin{gathered} 5\frac{1}{2}=\frac{2\times5+1}{2}=\frac{11}{2} \\ \frac{\frac{11}{2}}{\frac{1}{4}}=\frac{11}{2}\times4=\frac{44}{2}=22 \end{gathered}[/tex]We kept the denominator then multiplied it by the whole number and added it to 1. So it will last 22 meals.
5) To find it out we are going to divide 7 1/3 by 2/3 meter, after converting that Mixe Number into an Improper Fraction:
[tex]\begin{gathered} 7\frac{1}{3}=\frac{3\times7+1}{3}=\frac{22}{3} \\ \frac{\frac{22}{3}}{\frac{2}{3}}=\frac{22}{3}\times\frac{3}{2}=\frac{66}{6}=11 \end{gathered}[/tex]Notice, that we have used the same procedure to convert from Mixed Numbers to an Improper fraction.

And those are the answers.
