TL;DR

This video explains how to compare and calculate rates of volume per fish in different fish tanks.

Key Insights

• 🐟 Each tank has a different volume of water and number of fish, resulting in varying rates of volume per fish.
• 🐟 Calculating volume per fish involves dividing the volume of water in the tank by the number of fish.
• 🐡 Tank B has the highest volume per fish, followed by Tank A, and Tank C has the lowest volume per fish.

Transcript

• [Voiceover] Let's get some practice comparing and computing rates. So they tell us the pet store has three fish tanks, each holding a different volume of water and a different number of fish. So Tank A has five fish, and it has 40 liters of water, Tank B, 12 fish, 100 liters of water, and Tank C, 23 fish, and it has 180 liters of water. Order the... Read More

Questions & Answers

Q: How can the volume per fish be calculated?

The volume per fish can be calculated by dividing the volume of water in the tank by the number of fish in the tank. This gives us the rate at which water needs to be added per fish.

Q: How can improper fractions be converted to mixed numbers?

To convert an improper fraction (e.g., 100/12) to a mixed number, divide the numerator by the denominator. The whole number part is the result of the division, and the remainder becomes the numerator of the fraction.

Q: How can the order of the tanks be determined based on volume per fish?

To determine the order, calculate the volume per fish for each tank and compare them. The tank with the smallest volume per fish is ranked first, followed by the tank with the second smallest, and so on.

Q: What is the volume per fish for Tank B?

The volume per fish for Tank B is 8 1/3 liters. This means that for every fish in Tank B, 8 1/3 liters of water needs to be added.

Summary & Key Takeaways

• The video discusses three fish tanks (A, B, and C) with different volumes of water and numbers of fish.

• Tank A has 40 liters of water and 5 fish, resulting in a rate of 8 liters per fish.

• Tank B has 100 liters of water and 12 fish, resulting in a rate of 8 1/3 liters per fish.

• Tank C has 180 liters of water and 23 fish, resulting in a rate of 7 and 19/13 liters per fish.
