1. Solve Exercise 1 - Grade 5 Page 78 Math Book
Problem:
The number of high-achieving students at Van Thinh School is 552, accounting for 92% of the total students. How many students does Van Thinh School have?
Solution Method:
- Summary:
552 students: 92% of the total school
School has:... students?
- Solution Approach:
Find the number of school students by multiplying the number of high-achieving students by 92% (or multiply by 100, then divide by 92).
Answer:
Van Thinh School has the number of students:
552 : 92 x 100 = 600 (students)
Answer: 600 students
2. Solve Exercise 2 - Grade 5 Page 78 Math Book
Problem:
When inspecting a product from a tailoring workshop, 732 products are found to meet the standard, accounting for 91.5% of the total products. Calculate the total number of products.
Solution Method:
Calculate the total number of products by multiplying the number of standard products by 91.5% (or multiply by 100, then divide by 91.5).
Answer:
The total products of the workshop are:
732 : 91.5 x 100 = 800 (products)
The total products of the workshop are:
732 : 91.5 x 100 = 800 (products)
Answer: 800 products
3. Solve Exercise 3 - Grade 5 Page 78 Math Book
Problem:
A warehouse contains jasmine rice and sticky rice, with 5 tons of sticky rice. Mentally calculate the total amount of rice in the warehouse, if the sticky rice accounts for:
a) 10% of the total rice in the warehouse.
b) 25% of the total rice in the warehouse.
Solution Method:
Method 1: Calculate the total amount of rice in the warehouse by multiplying the amount of sticky rice by a% (or multiply by a, then divide by 100).
Method 2: Convert the percentage to a fraction, then calculate the total amount of rice in the warehouse by dividing the tons of sticky rice by the fraction obtained.
Answer:
Mental Calculation Method 1:
a) The amount of rice in the warehouse is:
5 x 100 : 10 = 500 : 10 = 50 (tons)
b) The amount of rice in the warehouse is:
5 x 100 : 25 = 500 : 25 = 20 (tons)
Mental Calculation Method 2:
10% = 1/10 ; 25% = 1/4
a) The amount of rice in the warehouse is: 5 x 10 = 50 (tons)
b) The amount of rice in the warehouse is: 5 x 4 = 20 (tons)
Answer: a) 50 tons.
b) 20 tons
