\( 3.72 + 1.28 = 5.00 \)

4. 15% of 40 =
\( 15\% \) of 40 means:
\( \frac{15}{100} \times 40 = 0.15 \times 40 = 6 \)
So, the answer is: 6

5. Factors of 16 are:
The factors of 16 are the numbers that divide 16 evenly:
\( 1, 2, 4, 8, 16 \)
So, the answer is: 1, 2, 4, 8, 16

6. Circle even numbers:
From the list: 12, 36, 44, 35

Wednesday

1. 2.05 × 12 =
Perform the multiplication:
\( 2.05 \times 12 = 24.60 \)
So, the answer is: 24.6

2. 1.50 ÷ 0.5 =
Perform the division:
\( 1.50 \div 0.5 = 3.00 \)
So, the answer is: 3

3. 3.65 × 0.7 =
Perform the multiplication:
\( 3.65 \times 0.7 = 2.555 \)
So, the answer is: 2.555

4. 5.60 ÷ 0.7 =
Perform the division:
\( 5.60 \div 0.7 = 8.00 \)
So, the answer is: 8

5. First 5 multiples of 6:
The first 5 multiples of 6 are:
\( 6 \times 1 = 6 \)
\( 6 \times 2 = 12 \)
\( 6 \times 3 = 18 \)
\( 6 \times 4 = 24 \)
\( 6 \times 5 = 30 \)
So, the answer is: 6, 12, 18, 24, 30

6. Circle prime numbers:
From the list: 11, 36, 44, 35
Prime numbers are: 11

7. Simplify: 8 × 3 = 320 ÷ ?
First, calculate \( 8 \times 3 \):
\( 8 \times 3 = 24 \)
Now, solve for the missing number in \( 320 \div ? = 24 \):
\( ? = 320 \div 24 = 13.33 \) (repeating)
So, the answer is: 13.33

8. How many m in 1km?
There are 1,000 m in 1 km.
