Guidance on solving exercise 3 on page 19 of Math 4 textbook
Problem Statement:
Fill in the blanks to form three consecutive natural numbers:
a) 4; 5;... b) ....; 87; 88
c) 896; ...898. d) 9; 10;.....
e) 99; 100;.... g) 9998; 9999;....
Solution Approach:
Students need to understand the following rules:
- Unknown consecutive number after it = Known consecutive number before it + 1.
- Unknown consecutive number before it = Known consecutive number after it - 1.
Answers:
a) The number to be filled in is the consecutive number after 5.
The consecutive number after 5 is 6;
We get the sequence: 4; 5; 6.
b) The number to be filled in is the consecutive number before 87.
The consecutive number before 87 is 86;
We get the sequence: 86; 87; 88.
c) The number to be filled in is the consecutive number after 896.
The consecutive number after 896 is 897;
We get the sequence: 896; 897; 898.
d) The number to be filled in is the consecutive number after 9 999.
The consecutive number after 9 999 is 10 000;
We get the sequence: 9 998; 9 999; 10 000.
