What will b and c be? Write down repeated addition, multiplication and division sums for the following: b. i. 8 rows of 8. ii. 5 rows of 8.

Here are the solutions for the multiplication and division problems.

1. What will b and c be? Write down repeated addition, multiplication and division sums for the following:

• b.

  • i. There are 8 rows of 8.
  • ii. Repeated addition: $8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 = \boxed{64}$
  • iii. Multiplication: $8 \times 8 = \boxed{64}$
  • iv. Division: $64 \div 8 = \boxed{8}$

• c. Homework

  • i. There are 5 rows of 8.
  • ii. Repeated addition: $8 + 8 + 8 + 8 + 8 = \boxed{40}$
  • iii. Multiplication: $5 \times 8 = \boxed{40}$
  • iv. Division: $40 \div 5 = \boxed{8}$

2. Complete the following:

• Multiplication (8x table):

  • $1 \times 8 = \boxed{8}$
  • $2 \times 8 = \boxed{16}$
  • $3 \times 8 = \boxed{24}$
  • $4 \times 8 = \boxed{32}$
  • $5 \times 8 = \boxed{40}$
  • $6 \times 8 = \boxed{48}$
  • $7 \times 8 = \boxed{56}$
  • $8 \times 8 = \boxed{64}$
  • $9 \times 8 = \boxed{72}$
  • $10 \times 8 = \boxed{80}$

• Division (8x table):

  • $16 \div 8 = \boxed{2}$
  • $32 \div 8 = \boxed{4}$
  • $56 \div 8 = \boxed{7}$
  • $48 \div 8 = \boxed{6}$
  • $72 \div 8 = \boxed{9}$
  • $24 \div 8 = \boxed{3}$
  • $40 \div 8 = \boxed{5}$
  • $8 \div 8 = \boxed{1}$
  • $64 \div 8 = \boxed{8}$
  • $80 \div 8 = \boxed{10}$

• Multiplication (9x table):

  • $1 \times 9 = \boxed{9}$
  • $2 \times 9 = \boxed{18}$
  • $3 \times 9 = \boxed{27}$
  • $4 \times 9 = \boxed{36}$
  • $5 \times 9 = \boxed{45}$
  • $6 \times 9 = \boxed{54}$
  • $7 \times 9 = \boxed{63}$
  • $8 \times 9 = \boxed{72}$
  • $9 \times 9 = \boxed{81}$
  • $10 \times 9 = \boxed{90}$

• Division (9x table):

  • $18 \div 9 = \boxed{2}$
  • $36 \div 9 = \boxed{4}$
  • $54 \div 9 = \boxed{6}$
  • $72 \div 9 = \boxed{8}$
  • $81 \div 9 = \boxed{9}$
  • $27 \div 9 = \boxed{3}$
  • $45 \div 9 = \boxed{5}$
  • $9 \div 9 = \boxed{1}$
  • $63 \div 9 = \boxed{7}$
  • $90 \div 9 = \boxed{10}$
