1. Solve problem 1 on page 45 of Grade 5 Math textbook
Problem:
Fill in the appropriate decimal numbers:
a) 4 tons 562kg = ... tons;
b) 3 tons 14kg = ... tons;
c) 12 tons 6kg =.... tons;
d) 500kg = ... tons.
Solution method:
- Step 1: Find the relationship between the given units of weight
- Step 2: Convert the weight measurements into mixed numbers containing decimal fractions based on the larger unit of weight
- Step 3: Convert weight units into decimal fractions corresponding to length measurements in decimal form with a larger weight unit.
2. Solve problem 2 on page 45 of Grade 5 Math textbook
Problem:
Write the following measurements in decimal form:
a) With kilogram unit:
2kg 50g; 45kg 23g; 10kg 3g; 500g.
b) With ton unit:
2 tons 50kg; 3 tons 3kg; 34 kg; 450kg
Solution method:
Refer to the solution method for a similar exercise in the Solve problem 1 on page 45 of Grade 5 Math textbook section.
3. Solve problem 3 on page 45 of Grade 5 Math textbook
Problem:
In the zoo, there are 6 lions, on average each eats 9 kg of meat per day. How many tons of meat are needed to feed that number of lions for 30 days?
Solution method:
- Given:
+ There are: 6 lions
+ 1 lion consumes 9kg of meat per day
- Required: Calculate the number of tons of meat needed to feed the lions for 30 days
- Solution:
+ Calculate the amount of meat 6 lions consume in 1 day by multiplying the amount of meat 1 lion consumes in 1 day by 6 (lions)
+ Calculate the amount of meat 6 lions consume in 30 days by multiplying the previous result by 30 (days).
+ Convert the weight unit from kg to tons and conclude.
Answer:
In one day, 6 lions consume:
9 x 6 = 54 (kg)
In 30 days, 6 lions consume:
54 x 30 = 1620 (kg) or 1.62 tons
Answer: 1.62 tons of meat.
