A. There are 0.35 hectoliters in 35 deciliters.
B. There are 7.62 centiliters in 762 liters.
C. There are 6.8 kiloliters in 68 hectoliters.
D. There are 0.75 deciliters in 7.5 liters.

Answer :

Let's go through each statement and check whether they are true or false using the metric conversion table:

1. Statement 1: "There are 0.35 hectoliters in 35 deciliters."

- According to the metric conversion table:
- 1 hectoliter = 100 deciliters.

- To convert 35 deciliters to hectoliters, divide by 100:
- [tex]\[ \text{Hectoliters} = \frac{35}{100} = 0.35 \text{ hectoliters} \][/tex]

- This statement is true.

2. Statement 2: "There are 7.62 centiliters in 762 liters."

- According to the metric conversion table:
- 1 liter = 100 centiliters.

- To convert 762 liters to centiliters, multiply by 100:
- [tex]\[ \text{Centiliters} = 762 \times 100 = 76,200 \text{ centiliters} \][/tex]

- The converted value doesn't match 7.62 centiliters, so this statement is false.

3. Statement 3: "There are 6.8 kiloliters in 68 hectoliters."

- According to the metric conversion table:
- 1 kiloliter = 10 hectoliters.

- To convert 68 hectoliters to kiloliters, divide by 10:
- [tex]\[ \text{Kiloliters} = \frac{68}{10} = 6.8 \text{ kiloliters} \][/tex]

- This statement is true.

4. Statement 4: "There are 0.75 deciliters in 7.5 liters."

- According to the metric conversion table:
- 1 liter = 10 deciliters.

- To convert 7.5 liters to deciliters, multiply by 10:
- [tex]\[ \text{Deciliters} = 7.5 \times 10 = 75 \text{ deciliters} \][/tex]

- The converted value doesn't match 0.75 deciliters, so this statement is false.

In conclusion, the true statements are:
- "There are 0.35 hectoliters in 35 deciliters."
- "There are 6.8 kiloliters in 68 hectoliters."
