Let’s solve each problem step by step.

Problem 4: Draw 3 more sets and fill in the blanks
You’re shown
5 groups of colorful balls arranged in pyramids. Each group has
6 balls (3 on bottom, 2 in middle, 1 on top).
So, we have:
> _6_ + _6_ + _6_ + _6_ + _6_ = _30_
That’s
5 groups of 6 = 30.
In multiplication form:
> So _5_ × _6_ = _30_.
You are asked to
draw 3 more sets — that means draw 3 more pyramids of 6 balls each.
Then you’d have
8 total groups of 6.
But since the question only asks to fill in the blanks for the current image (which shows 5 groups), we’ll fill based on what’s visible.
✔ Final Answer for #4:
>
6 + 6 + 6 + 6 + 6 = 30
>
5 groups of 6 = 30. So 5 × 6 = 30.
*(Note: You should draw 3 more identical pyramid sets in the blank boxes.)*

Problem 6: Fill in the blanks.
We need to find the missing factor.
a. 28 × ___ = 280 → Divide 280 ÷ 28 =
10
b. ___ × 25 = 250 → 250 ÷ 25 =
10
c. 16 × ___ = 1600 → 1600 ÷ 16 =
100
d. ___ × 68 = 6800 → 6800 ÷ 68 =
100
e. ___ × 15 = 1500 → 1500 ÷ 15 =
100
f. ___ × 8600 = 0 → Any number × 0 = 0 → So answer is
0

Problem 7: Find the product.
Multiply the numbers.
a. 32 × 40
→ 32 × 4 = 128, then add a zero →
1,280
b. 82 × 90
→ 82 × 9 = 738, then add a zero →
7,380
c. 368 × 20
→ 368 × 2 = 736, then add a zero →
7,360
d. 333 × 30
→ 333 × 3 = 999, then add a zero →
9,990
e. 16 × 300
→ 16 × 3 = 48, then add two zeros →
4,800
f. 56 × 80
→ 56 × 8 = 448, then add a zero →
4,480
