Explanation:

Problem 5 (Multiplication Equations)

We'll solve each multiplication equation step by step.

For \( 4 \times 7 \):

Step 1: Recall multiplication table

Using the 4 times table, \( 4 \times 7 = 28 \)

For \( 6 \times 5 \):

Step 1: Recall multiplication table

Using the 6 times table, \( 6 \times 5 = 30 \)

For \( 6 \times 2 \):

Step 1: Recall multiplication table

Using the 6 times table, \( 6 \times 2 = 12 \)

For \( 5 \times (1 + 6) \):

Step 1: Simplify the parentheses

First, calculate \( 1 + 6 = 7 \)

Step 2: Multiply

Then, \( 5 \times 7 = 35 \)

For \( 4 \times 6 \):

Step 1: Recall multiplication table

Using the 4 times table, \( 4 \times 6 = 24 \)

For \( 4 \times 1 \):

Step 1: Recall multiplication table

Using the 4 times table, \( 4 \times 1 = 4 \)

For \( 6 \times 7 \):

Step 1: Recall multiplication table

Using the 6 times table, \( 6 \times 7 = 42 \)

For \( 7 \times 3 \):

Step 1: Recall multiplication table

Using the 7 times table, \( 7 \times 3 = 21 \)

For \( 7 \times 4 \):

Step 1: Recall multiplication table

Using the 7 times table, \( 7 \times 4 = 28 \)

For \( 7 \times 7 \):

Step 1: Recall multiplication table

Using the 7 times table, \( 7 \times 7 = 49 \)

For \( 8 \times 2 \):

Step 1: Recall multiplication table

Using the 8 times table, \( 8 \times 2 = 16 \)

For \( 8 \times 5 \):

Step 1: Recall multiplication table

Using the 8 times table, \( 8 \times 5 = 40 \) (Note: The handwritten answer in the image seems incorrect here; the correct answer is 40)

For \( 8 \times (2 + 5) \):

Step 1: Simplify the parentheses

First, calculate \( 2 + 5 = 7 \)

Step 2: Multiply

Then, \( 8 \times 7 = 56 \)

For \( 5 \times 1 \):

Step 1: Recall multiplication table

Using the 5 times table, \( 5 \times 1 = 5 \)

For \( 5 \times 6 \):

Step 1: Recall multiplication table

Using the 5 times table, \( 5 \times 6 = 30 \)

Problem 6 (Starfish Arms)

Step 1: Find total number of starfish

Anica sees 4 starfish and her brother sees 3 starfish. So total starfish \( = 4 + 3 = 7 \)

Step 2: Calculate total arms

Each starfish has 5 arms. So total arms \( = 7 \times 5 \)

Step 3: Multiply

\( 7 \times 5 = 35 \)

Answer:

The total number of arms on the starfish Anica and her brother see is 35.
