= 77.077 L.

Question 9.

1 kL + 35 L = ___________ L

Answer:

1 kL + 35 L = 1,035 L.

Explanation:

1 kL + 35 L = ?? L.

Conversion:

1 kL = 1000 L.

1 kL + 35 L = (1,000 × 1) + 35

= 1,000 + 35

= 1,035 L.

Question 10.

41 mL + 41 L = ___________ kL

Answer:

41 mL + 41 L = 0.041041 kL.

Explanation:

41 mL + 41 L = ?? kL.

Conversion:

1 kL = 1000 L.

1 kL = 10,00,000 mL.

41 mL + 41 L = (41 ÷ 10,00,000) + (41 ÷ 1,000)

= 0.000041 + 0.041

= 0.041041 kL.

Question 11.

4 kL – 325 L = ___________ L

Answer:

4 kL – 325 L = 3,675 L.

Explanation:

4 kL – 325 L = ?? L.

Conversion:

1 kL = 1,000 L.

4 kL – 325 L = (4 × 1,000) – 325

= 4000 – 325

= 3,675 L.

Question 12.

35 kL + 3500 L = ___________ kL

Answer:

35 kL + 3500 L = 38.5 kL.

Explanation:

35 kL + 3500 L = ?? kL.

Conversion:

1 kL = 1,000 L.

35 kL + 3500 L = 35 + (3,500 ÷ 1,000)

= 35 + 3.5

= 38.5 kL.

Question 13.

23 L + .23 mL = _________ L

Answer:

23 L + .23 mL = 23.00023 L.

Explanation:

23 L + .23 mL = ?? L.

Conversion:

1 L = 1,000 mL.

23 L + .23 mL = 23 + (0.23 ÷ 1,000)

= 23 + 0.00023

= 23.00023 L.

Question 14.

41 L – 23 mL = _________ mL

Answer:

41 L – 23 mL = 40,977 mL.

Explanation:

41 L – 23 mL = ?? mL.

Conversion:

1 L = 1,000 mL.

41 L – 23 mL = (41 × 1000) – 23

= 41,000 – 23

= 40,977 mL.

Question 15.

If a water cooler holds 30 liters of water, and each cup of water holds 250 milliliters, how many cups can you fill before the water cooler is empty?

Answer:

Number of water cups can fill before the water cooler is empty = 120.

Explanation:

Number of liters of water a water cooler holds = 30.

Number of milliliters each cup of water holds = 250.

Conversion:

1 L = 1,000 mL.

Number of milliliters of water a water cooler holds = 30 L = 1000 × 30 = 30,000 mL.

Number of water cups can fill before the water cooler is empty = Number of milliliters of water a water cooler holds ÷ Number of milliliters each cup of water holds

= 30,000 ÷ 250

= 120.

Question 16.

If there are 35 students and each expects to drink 10 half-liter bottles of water in a week, how many many total liters is this?

Answer:

Total number of liters bottles of water they drank = 700 L.

Explanation:

Number of students = 35.

Number of half liters bottles of water in a week each expects to drink = 10.

Conversion:

=> 10 half liters = 5 liters.

Total number of half liters bottles of water they drank = Number of students × Number of half liters bottles of water in a week each expects to drink

= 35 × 10

= 350.

Conversion:

1 L = half liter + half liter.

Total number of liters bottles of water they drank =

=> 350 half liters = 350 + 350 L.

=> 700 L.

Question 17.

A half-liter bottle of soda is a common size. How many bottles of soda would it take to fill a 10-liter container?

Answer:

Number of half-liter bottle of soda it takes to fill a 10-liter container = 20.

Explanation:

Number of liters container = 10.

Conversion:

1 L = half-liter + half-liter

=> Number of half-liter bottle of soda it takes to fill a 10-liter container = Number of liters container × 2

= 10 × 2

= 20.

Question 18.

If a reservoir holds 100,000,000 liters of water, then how many kiloliters of water does it hold?

Answer:

Number of kiloliters of water it holds = 100,000.

Explanation:

Number of liters of water a reservoir holds = 100,000,000.

Conversion:

1 kL = 1,000 L.

=> Number of kiloliters of water it holds = 100,000,000 ÷ 1,000

=> 100,000.
