Exercise 5.
a. 1/9 of 72 kg is: ............. kg
b. Folding the number 9 seven times and then adding 9 gives the result: ...........
c. Quick calculation: 9 x 7 + 9 x 3 = ..........
* Answers:
Exercise 1. Calculate: 872 : 4 = 218, 365 : 5 = 73; 390: 6 = 65; 350 : 7 = 50;
361 : 3 = 120 (remainder 1); 486 : 8 = 60 (remainder 6); 452 : 9 = 50 (remainder 2)
Exercise 2.
Summary:
Ink pens: 9 pens : 72,000 dong ; 1 pen : ....dong?
Notebooks: 4 notebooks : 36,000 dong ; 1 notebook: ....dong?
Solution:
The price of 1 ink pen is: 72,000 : 9 = 8000 (dong)
The price of 1 notebook is: 36,000 : 4 = 9000 (dong)
Answer: ink pen: 8000 dong; notebook: 9000 dong
Exercise 3.
Summary:
A large container holds 36 liters of gasoline
A small container holds 9 liters of gasoline.
Solution:
The number of times the large container holds the same amount of gasoline as the small container:
36:9= 4(times)
So, the small container holds 1/4 of the gasoline in the large container
Answer: 1/4
Exercise 4.
Summary:
9 pages: 1 day
137 pages: .... days?
Solution:
We have: 137 : 9 = 15 (days) remainder 2 (pages)
2 pages also require 1 day to read.
So, the number of days for Minh to finish reading the book is:
15 + 1 = 16 (days)
Answer: 16 days.
