Solving Exercise 2 on page 24 Math 4 textbook in the Mass Measurement Unit Table, Calculation

Guidelines for solving Exercise 2 page 24 Math 4 textbook

Problem:
Calculate
380 g + 195 g 452 hg x 3
928 dag - 274 dag 768 hg : 6

Solution Method:
* Observation: All numbers in the expression have the same unit of mass.
* Procedure: Perform addition, subtraction, multiplication, and division as usual; after obtaining the result, remember to include the accompanying unit of mass.

Answer:
+) 380 g + 195 g +) 928 dag - 274 dag
We have: 380 + 195 = 575 So, 380 g + 195 g = 575 g So, 928 dag - 274 dag = 654
+) 452 hg x 3 +) 768 hg : 6
We have: 452 x 3 = 1 356 So, 452 hg x 3 = 1 356 hg So, 768 hg : 6 = 128 hg

Frequently Asked Questions

What are the key steps to solve Exercise 2 in the Math 4 textbook?

To solve Exercise 2 in the Math 4 textbook, students should first ensure that all numbers are in the same unit of mass. Then, they should perform addition, subtraction, multiplication, and division as required, and remember to include the appropriate mass unit in the final answer. For example, when adding 380 g and 195 g, the result is 575 g.

How should students handle units when performing mass calculations in math?

Students should always ensure that the units of mass are consistent before performing any calculations. For example, if the exercise includes grams, hectograms, and decagrams, students must convert them to the same unit before adding, subtracting, multiplying, or dividing to avoid errors in their final answers.

Why is it important to include units in mass measurements during calculations?

Including units in mass measurements is crucial because it provides clarity and ensures accuracy in calculations. Without units, the results can be misleading or incorrect. For instance, stating that 380 g + 195 g equals 575 without specifying 'grams' would create confusion about the measurement being referred to.

What types of operations are required in Exercise 2 of the Math 4 textbook?

Exercise 2 of the Math 4 textbook requires students to perform several operations, including addition, subtraction, multiplication, and division. For example, they must add 380 g and 195 g, and then multiply 452 hg by 3. Mastering these operations enhances their mathematical skills in handling mass measurements.
