Guidelines for solving exercises on page 22 Math 4 including solving methods
1. Solve exercise 1 on page 22 Math 5 textbook
Solution method:
Comparison rule for two numbers:
- The number with more digits is greater, and vice versa, the number with fewer digits is smaller.
- When two numbers have the same number of digits: Compare each pair of digits in the same position from left to right:
+ The number with the larger digit at the same position is greater
+ If two numbers have the same digit pairs in the same position, then the two numbers are equal.
2. Solve exercise 2 on page 22 Math 5 textbook
Problem statement:
Write the following numbers in ascending order:
a) 8 316; 8 136; 8 361.
b) 5 724; 5 742; 5 740.
c) 64 831; 64 813; 63 841.
Solution method:
- Observation: All given numbers have the same number of digits
- Solution:
+ Step 1: Compare each pair of digits in the same position from left to right. The number with the larger digit at the same position is greater, and vice versa.
+ Step 2: After comparing the numbers, arrange them in the required order.
Answers:
a) The comparison of numbers yields the following result:
8 136; 8 316; 8 361.
b) The comparison of numbers yields the following result:
5 724; 5 740; 5 742
c) The comparison of numbers yields the following result:
64813; 64831; 63841
3. Solve exercise 3 on page 22 Math 5 textbook
Problem statement:
Write the following numbers in descending order:
a) 1 942; 1 978; 1 952; 1 984. b) 1 890; 1 945; 1 969; 1 954.
Solution method:
>>> Refer to detailed guidance on solving Exercise 2 on page 22 Math 5 textbook.
Answers:
