1. All odd numbers less than 9 are irranged in a descending order a) Write down the number formet in i) Figures ii) Wonds b) What is the total value of the third digit in the number? Express each of the following as a product of its prime factors a) 594 b) 960 c) 30375 d) 2025

\( 1+6+11+16+.....+56= \)

\( \frac{1+6+11+16.....+56}{(-1)+(-11)+(-21).....+(-51)} \)

3. Ivaluato without using calculator a) \( \frac{-12 \div(-3) \times 4-(-20)}{-6 \times 6 \div 3+(-6)} \) b) \( \frac{-4+(-3) \text { of } 9+1 \times 14 \div 2)}{4+2 \text { of } 3-(-10 \div 5)} \) Simplify \( \frac{6}{7}+4 \frac{4}{5} \times 1 / 6 \div 1 / 6 \) \( 8 / 11-4 / 5 \times 2 / 6 \)
