2. Solving Exercise 2 - Math Workbook Grade 4 Volume 2 Page 115
Problem Statement:
a) 3 swallows = ....kg;
1 swallow and 5kg equals .... kilograms;
50 kilograms equals .... swallows;
b) 6 piculs equals .... kilograms;
2 piculs and 25 kilograms equals .... kilograms;
500 kilograms equals .... piculs;
9 piculs equals .... swallows;
3 piculs and 5 kilograms equals .... kilograms;
1000 kilograms equals .... piculs equals .... tons
c) 1 ton = .... kilograms;
2 tons = .... kilograms;
5000 kilograms = .... tons;
1 ton = .... piculs;
12 tons = .... kilograms;
4 tons 70 kilograms = .... kilograms;
Solution Method
Based on the unit conversion table.
Answer:
a) 3 swallows = 30kg;
1 swallow and 5kg = 15 kg;
50kg = 5 swallows
b) 6 piculs = 600 kg;
2 piculs and 25 kg = 225kg;
500kg = 5 piculs;
9 piculs = 90 swallows;
3 piculs and 5 kg = 305kg;
1000kg = 10 piculs = 1 ton
c) 1 ton = 1000kg;
2 tons = 2000kg;
5000 kilograms = 5 tons;
1 ton = 10 quintals;
12 tons = 12000 kilograms;
4 tons 70 kilograms = 4070 kilograms

4. Solve problem 4 - Math Workbook Grade 4 Volume 2 Page 116
Problem Statement:
The problem: There are 40 students practicing singing, where the number of male students equals 3/5 of the number of female students. How many male students are practicing singing?
Solution Method
1. Draw a diagram: consider the number of male students as 3 equal parts, then the number of female students is divided into 5 equal parts accordingly.
2. Find the total number of equal parts.
Find the value of one part by taking the sum of two numbers divided by the total number of equal parts.
Find the number of male students practicing singing (multiply the value of one part by the number of parts representing the number of male students).
Note: Steps 3 and 4 can be combined into one step.
Answer
As per the problem, the total number of equal parts is:
3 + 5 = 8 (parts)
The number of male students practicing singing is:
40 : 8 x 3 = 15 (students)
The answer is: 15 students
