Let’s solve this step by step.

We need to remember the basic conversions:

- 1 gallon = 4 quarts
- 1 quart = 2 pints
- 1 pint = 2 cups

So we can also say:
- 1 gallon = 8 pints (because 4 quarts × 2 pints)
- 1 gallon = 16 cups (because 8 pints × 2 cups)
- 1 quart = 4 cups (because 2 pints × 2 cups)

Now let’s go problem by problem.

---

Section 1: Fill in the blanks

1) 1 gallon = ___ cups → 16 cups
2) 3 quarts = ___ pints → 3 × 2 = 6 pints
3) 7 gallons = ___ pints → 7 × 8 = 56 pints
4) 9 quarts = ___ cups → 9 × 4 = 36 cups
5) 2 gallons = ___ pints → 2 × 8 = 16 pints
6) ___ quarts = 14 cups → 14 ÷ 4 = 3.5 quarts? Wait — but all answers should be whole numbers? Let me check: 14 cups ÷ 4 = 3.5 → that’s not a whole number. But maybe it’s okay? Or did I misread? Actually, looking again — perhaps it’s meant to be exact. Let’s hold on and come back if needed. For now, 14 ÷ 4 = 3.5 → so 3.5 quarts. But since other problems use whole numbers, maybe it’s a typo? No — actually, 14 cups is 3 quarts and 2 cups, which is 3.5 quarts. So answer is 3.5. But let’s see what the worksheet expects. Maybe they want fractions? We’ll write 3.5 or 7/2? But for now, let’s keep going.

Wait — let me double-check the conversion: 1 quart = 4 cups → yes. So 14 cups = 14 ÷ 4 = 3.5 quarts. Okay.

7) 8 quarts = ___ pints → 8 × 2 = 16 pints
8) 2 gallons = ___ cups → 2 × 16 = 32 cups
9) ___ pints = 3 gallons → 3 × 8 = 24 pints
10) ___ quarts = 12 pints → 12 ÷ 2 = 6 quarts
11) 2 gallons = ___ quarts → 2 × 4 = 8 quarts
12) 16 pints = ___ gallons → 16 ÷ 8 = 2 gallons
13) ___ gallons = 12 quarts → 12 ÷ 4 = 3 gallons
14) 16 quarts = ___ cups → 16 × 4 = 64 cups
15) 9 quarts = ___ cups → 9 × 4 = 36 cups
16) 7 quarts = ___ pints → 7 × 2 = 14 pints
17) ___ quarts = 24 pints → 24 ÷ 2 = 12 quarts
18) 10 gallons = ___ pints → 10 × 8 = 80 pints
19) 32 quarts = ___ gallons → 32 ÷ 4 = 8 gallons
20) ___ cups = 9 quarts → 9 × 4 = 36 cups

Okay, done with section 1.

Section 2: Which is most? Circle the largest amount in each box.

First box:
- 15 cups
- 3 gallons → 3 × 16 = 48 cups → bigger than 15
- 5 quarts → 5 × 4 = 20 cups
- 6 quarts → 6 × 4 = 24 cups
→ Largest is 3 gallons (48 cups)

Second box:
- 2 quarts → 8 cups
- 9 cups
- 16 pints → 16 × 2 = 32 cups
- 33 cups
→ Largest is 33 cups

Third box:
- 7 quarts → 28 cups
- 16 pints → 32 cups
- 33 cups
- 19 cups
→ Largest is 33 cups

Fourth box:
- 14 cups
- 3 quarts → 12 cups
- 7 pints → 14 cups
- 1 gallon → 16 cups
→ Largest is 1 gallon (16 cups)

Wait — 14 cups vs 16 cups → yes, 1 gallon wins.

But let me confirm: 1 gallon = 16 cups → correct.

So answers:

Box 1: 3 gallons
Box 2: 33 cups
Box 3: 33 cups
Box 4: 1 gallon

Section 3: Put these liquid measures in order from smallest to largest.

Given:
- 2 gallons
- 7 quarts
- 30 cups
- 13 pints

Convert all to cups to compare easily.

- 2 gallons = 2 × 16 = 32 cups
- 7 quarts = 7 × 4 = 28 cups
- 30 cups = 30 cups
- 13 pints = 13 × 2 = 26 cups

Now list in cups:
26 cups (13 pints), 28 cups (7 quarts), 30 cups, 32 cups (2 gallons)

So order from smallest to largest:
13 pints, 7 quarts, 30 cups, 2 gallons

Now let’s compile all answers.

Final Answer:

Section 1:
1) 16
2) 6
3) 56
4) 36
5) 16
6) 3.5 (or 7/2)
7) 16
8) 32
9) 24
10) 6
11) 8
12) 2
13) 3
14) 64
15) 36
16) 14
17) 12
18) 80
19) 8
20) 36

Section 2:
Box 1: 3 gallons
Box 2: 33 cups
Box 3: 33 cups
Box 4: 1 gallon

Section 3:
Smallest to largest: 13 pints, 7 quarts, 30 cups, 2 gallons

Note: For #6, if the worksheet expects whole numbers only, there might be an error — but mathematically, 14 cups = 3.5 quarts. If fractional answers are allowed, 3.5 is correct. Some worksheets might write it as 3½.

But since the rest are whole numbers, let me recheck #6: “___ quarts = 14 cups”

Is it possible it was meant to be 12 cups? Then it would be 3 quarts. Or 16 cups = 4 quarts. But as written, 14 cups = 3.5 quarts.

I think we have to go with 3.5.

Alternatively, maybe they expect mixed numbers? Like 3 1/2 quarts.

But for simplicity, I’ll write 3.5.

Actually, looking at the original image text — it says “___ quarts = 14 cups” — no indication of fraction, but math doesn’t lie.

Perhaps in context, they accept decimals.

I’ll proceed.

Final Answer:

1) 16
2) 6
3) 56
4) 36
5) 16
6) 3.5
7) 16
8) 32
9) 24
10) 6
11) 8
12) 2
13) 3
14) 64
15) 36
16) 14
17) 12
18) 80
19) 8
20) 36

Largest amounts:
First box: 3 gallons
Second box: 33 cups
Third box: 33 cups
Fourth box: 1 gallon

Order from smallest to largest: 13 pints, 7 quarts, 30 cups, 2 gallons
