Question 1.
Which is greater, 197,210 or 225,302?
Compare the values of the digits, working from left to right.

___ hundred thousands is greater than ___ is greater than
So, ___ is greater than ____
Place value in Maths describes the position or place of a digit in a number. Each digit has a place in a number. When we represent the number in general form, the position of each digit will be expanded. Those positions start from a unit place or we also call it one’s position. The order of place value of digits of a number of right to left is units, tens, hundreds, thousands, ten thousand, a hundred thousand, and so on.

A whole number is larger than another if it has more digits. If the number of digits in each number is the same, then look at the digits from left to right. If the left digit is larger in one number, then this is the largest number. If this digit is the same, compare the next digit along to the right.
Now compare the numbers: 197,210 and 222,302
1 is less than 2 so 197,210 is less than 222,302. Because In hundred thousand place 1 is smaller than 2.
197,210<222,302

Question 7.

Note: Least to greatest means ascending order.
Ascending order definition: Ascending order is a method of arranging numbers from smallest value to largest value. The order goes from left to right. Ascending order is also sometimes named as increasing order.
For example, a set of natural numbers are in ascending order, such as 1 < 2 < 3 < 4 < 5 < 6 < 7 < 8… and so on. The less than symbol (<), is used to denote the increasing order.

The word ‘ascending’ means going up. Hence, in the case of Mathematics, if the numbers are going up, then they are arranged in ascending order.
The other terms used for ascending order are:
1. Lowest value to highest value
2. Bottom value to Top value
These numbers can be written by using the ascending symbol: 315,679< 615,379< 739,615< 795,316.

Question 20.

It is an arithmetic pattern.
Definition: The arithmetic pattern is also known as the algebraic pattern. In an arithmetic pattern, the sequences are based on the addition or subtraction of the terms. If two or more terms in the sequence are given, we can use addition or subtraction to find the arithmetic pattern.

The given terms are 230,180    231,180    232, 180    –    –  Now find the missing term in the sequence.
Here, we can use the addition process to figure out the missing terms in the patterns.
In the pattern, the rule used is “Add 1 to the previous term to get the next term”.
Now take the second term 231, 180  If we add 1 to the second term (231), we get the third term (232) and the 180 repeats like that.
Similarly, we can find the unknown terms in the sequence.
First missing term: The previous term is 232. Therefore, 232+1 = 233.
Second missing term: The previous term is 233. So, 233+1 = 234.
Hence, the complete arithmetic pattern is 230, 180  231, 180  232, 180  233, 180  234,180.

Question 21.

It is an arithmetic pattern.
Definition: The arithmetic pattern is also known as the algebraic pattern. In an arithmetic pattern, the sequences are based on the addition or subtraction of the terms. If two or more terms in the sequence are given, we can use addition or subtraction to find the arithmetic pattern.

The given terms are 850, 400   845, 400    840, 400    –    –  Now find the missing term in the sequence.
Here, we can use the subtraction process to figure out the missing terms in the patterns.
In the pattern, the rule used is “subtract 5 to the previous term to get the next term”.
Now take the second term 845, 400  If we subtract 5 to the second term (845), we get the third term (840) and the 400 repeats like that.
Similarly, we can find the unknown terms in the sequence.
First missing term: The previous term is 840. Therefore, 840-5 = 835.
Second missing term: The previous term is 835. So, 835-5 = 830.
Hence, the complete arithmetic pattern is 850, 400  845, 400  840, 400,  835, 400  830, 400.

Question 22.

It is an arithmetic pattern.
Definition: The arithmetic pattern is also known as the algebraic pattern. In an arithmetic pattern, the sequences are based on the addition or subtraction of the terms. If two or more terms in the sequence are given, we can use addition or subtraction to find the arithmetic pattern.

The given terms are 2,650,719  3,650,719  4,650,719    –    –  Now find the missing term in the sequence.
Here, we can use the addition process to figure out the missing terms in the patterns.
In the pattern, the rule used is “Add 1,000,000 to the previous term to get the next term”.
Now take the second term 3,650,719  If we add 1,000,000 to the second term (3,650,719), we get the third term (4,650,719).
Similarly, we can find the unknown terms in the sequence.
First missing term: The previous term is 4,650,719. Therefore, 4,650,719+1,000,000=5,650,719.
Second missing term: The previous term is 5,650,719. So, 5,650,719+1,000,000=6,650,719.
Hence, the complete arithmetic pattern is 2,650,719   3,650,719    4,650,719    5,650,719    6,650,719.

Question 23.

It is an arithmetic pattern.
Definition: The arithmetic pattern is also known as the algebraic pattern. In an arithmetic pattern, the sequences are based on the addition or subtraction of the terms. If two or more terms in the sequence are given, we can use addition or subtraction to find the arithmetic pattern.

The given terms are 6,298,436   5,198,436  4,098,436   –    –  Now find the missing term in the sequence.
Here, we can use the subtraction process to figure out the missing terms in the patterns.
In the pattern, the rule used is “subtract 1,100,000 to the previous term to get the next term”.
Now take the second term 5,198,436  If we subtract 1,100,000 to the second term (5,198,436), we get the third term (4,098,436).
Similarly, we can find the unknown terms in the sequence.
First missing term: The previous term is 4,098,436. Therefore, 4,098,436-1,100,000=2,998,436.
Second missing term: The previous term is 2,998,436. So, 2,998,436-1,100,000=1,898,436.
Hence, the complete arithmetic pattern is 6,298,436  5,198,436  4,098,436  2,998,436  1,898,436.
