3. Divide. \( \begin{array}{lll}\text { a. } 1 \frac{5}{7} \div 1 \frac{3}{7} & \text { b. } 5 \div 3 \frac{3}{4} & \text { c. } 1 \frac{5}{6} \div 1 \frac{2}{9} \\ \begin{array}{lll}\text { d. } 5 \frac{1}{4} \div 4 \frac{1}{5} & \text { e. } 6 \frac{2}{5} \div 1 \frac{2}{5} & \text { f. } 1 \div 3 \frac{6}{7} \\ \text { g. } 8 \frac{1}{8} \div 1 \frac{5}{8} & \text { h. } 3 \frac{5}{8} \div 1 \frac{1}{6} & \text { i. } 6 \frac{1}{2} \div 3 \frac{3}{4}\end{array}\end{array} ⿴ \begin{array}{l}\end{array} \)

3.1. Simplify each of the following ratios: 3.1.1. \( 4: 28: 16 \) 3.1.2. \( 6: 1.25: 2.5 \) 3.1.3. \( 3.6: 27: 13.5 \) 3.2. Distribute \( R 24000.00 \) in the ratio 2:1:5.

Ex. 3 Simplify \( \left(9.6 \times 3.6 \div 7.2+10.8\right. \) of \( \left.\frac{1}{18}-\frac{1}{10}\right) \)

11. If the average (arithmetic mean) of five numbers is 4 and if four of the numbers are \( 1,3,5 \), and 7 , what is the fifth number? \( \begin{array}{llll}\text { (A) }-1 & \text { (B) } 0 & \text { (C) } & \text { (D) } 6\end{array} \) (E) 9 \( \$ \begin{array}{l}\text { (D) }\end{array} \)

Aşağıdaki sayıların 4 ile bölünebilmesi için gelebilecek rakamların tamamını yazınız. 4. \( 2 \square 6 \rightarrow \) 5. \( 25 \square \rightarrow \) \( 6.24 \square 0 \)

What is 100 degrees Celsius equal to in Fahrenheit?
