The carousel has 40 cabins with equal distances and the cabins are numbered a person gets on cahin number 3 . if the carousel rotates counter clockwise by the siore of \( \frac{47}{10} \) which cabin will this persun be in?

(4. Calculà y. si es posible. expresá el resultado como número mixto \( \frac{11}{10}+\frac{5}{2}= \) \( \frac{7}{9}+\frac{2}{3}= \) \( \frac{19}{5}-\frac{7}{3}= \) \( \frac{2}{5}+\frac{3}{2}= \)

12. Бастапқыда құны А теңге болатын кітап 30\%-ға қымбаттады. Одан кейін тағы 10\%-ға қымбаттап, ең соңында 50\%-ға арзандады. Кітаптың бағасы қанша теңге болды? (A) \( 0,9 A \) (B) \( 0,885 A \) (C) \( 0,785 A \) (D) \( 0,715 A \)

5. a) Puja Limbu did 8 out of 10 math problems and Raju Lama did 11 out of 15 similar math problems. Express the number of problems solved by each of them in fractions and identify who did better performance.

Calculer: \( (-3) \div(-2) ; 8 \div(-4) \quad ; \quad \frac{(-72}{9} \)
