Math in Focus Grade 2 Chapter 9 Practice 3 Answer Key Measuring in Liters 1

Question 1.
Math in Focus Grade 2 Chapter 9 Practice 3 Answer Key Measuring in Liters 2
Volume of water = ___ or ____
Answer: 2L
Math in Focus Grade 2 Chapter 9 Practice 3 Answer Key Measuring in Liters q1
Explanation:
1. Demonstrate what students will do by pouring water from a cup into a 100-mL graduated cylinder until it reaches a height that will cover the sample. This is the “initial water level.”
2. Tell students that the surface of the water in a tube may not be completely flat. Instead, the surface may curve in a shallow U-shape called the meniscus. When measuring, read the line just at the bottom of the meniscus.
3. Tilt the graduated cylinder and slowly slide the sample into the water. Hold the graduated cylinder upright. Record the level of the water. Point out that this is the “final water level.”
4. Tell students that you want to find out how much the water level changed. Subtract the initial water level from the final water level to find the volume of the rod.
5. Volume of sample = final water level − initial water level.
the volume of water=2-0
the volume of water=2.

Question 10.
Susan uses these volumes of juices to make fruit punch. Write the volume of each juice.
Math in Focus Grade 2 Chapter 9 Practice 3 Answer Key Measuring in Liters 12
Answer:
Math in Focus Grade 2 Chapter 9 Practice 3 Answer Key Measuring in Liters q10.1
Explanation:
Orange juice:
To calculate the volume of juice, there is a formula:
The volume of water=Final point-initial point
The volume of orange juice=2-0
The volume of orange juice=2
Grape juice:
The volume of watre=final point-initial point
The volume of grape juice=1-0
The volume of grape juice=1
Apple juice:
The volume of water=final point-initial point
The volume of apple juice=3-0
The volume of apple juice=3

Question 11.
The volume of ____ juice is more than the volume of orange juice.
Answer: apple juice.
Explanation:
The volume of orange juice is 2 litres.
The volume of apple juice is 3 litres.
As we know, 3 is greater than 2.
Therefore, 3>2.
So, the volume of apple juice is more than orange juice.

Question 12.
Susan used ___ liters more apple juice than grape juice.
Answer: 2 litres.
Explanation:
The volume of grape juice is 1 litres.
The volume of apple juice is 3 litres.
To calculate the number of litres more apple juice than grape juice we need to subtract both the volume then we get the result.
The difference: apple juice-grape juice
The difference:3-1
The difference:2
Therefore, 2 litres more apple juice than grape juice.

Question 13.
Susan used ___ litre more orange juice than apple juice.
Answer: 0 litres.
Explanation:
The volume of orange juice is 2 litres.
The volume of apple juice is 3 litres.
Actually, Susan used nothing more than apple juice. Because apple juice volume is more than orange juice. He can’t use more orange juice than apple juice.

Question 14.
Order the volumes of the juices from least to greatest in litres.
Math in Focus Grade 2 Chapter 9 Practice 3 Answer Key Measuring in Liters 13
Answer:
Math in Focus Grade 2 Chapter 9 Practice 3 Answer Key Measuring in Liters q14
Explanation:
In the question asked least to greatest, according to that we need to arrange the volume of juices.
1. The least is grape juice because it is 1 litre which compares to apple juice and orange juice.
2. The next one is some what least to apple juice and greatest to grape juice. That is orange juice which is the volume of 2 litres.
3. The last one is apple juice which is greater than orange juice and grape juice.
It is like an ascending order that means we need to arrange lowest to highest.
