Question 1: The following figures in comparison: <br> 36,814 and 36,841

36,814 and 36,841 (Correct answer)
36,841 < 36,814
36,814 > 36,841
36,841 = 36,814

Correct answer: 36,814 and 36,841

The question asks to compare the figures 36,814 and 36,841. The correct answer simply reiterates these two figures. This implies the question might be a setup for a subsequent comparison, or it is asking to identify the numbers themselves rather than performing the comparison operation.

Question 2: The following figures in comparison: <br> 83,412 and 83,421

83421 < 83,412
83,412 < 83,421 (Correct answer)
83,421 = 83,412
83,412 > 83,421

Correct answer: 83,412 < 83,421

To compare 83,412 and 83,421, we examine their place values from left to right. Both numbers share 8 in the ten thousands place, 3 in the thousands, and 4 in the hundreds. However, in the tens place, 83,412 has a 1, while 83,421 has a 2. Since 1 is less than 2, 83,412 is less than 83,421.

Question 3: The following figures in comparison: <br> 58,398 and 58,389

58,389 > 58,398
58,398 < 58,389
58,389 = 58,398
58,398 > 58,389 (Correct answer)

Correct answer: 58,398 > 58,389

To compare 58,398 and 58,389, we examine their digits from left to right. Both numbers share 5 in the ten thousands place, 8 in the thousands, and 3 in the hundreds. However, in the tens place, 58,398 has a 9, while 58,389 has an 8. Since 9 is greater than 8, 58,398 is greater than 58,389.

Question 4: Sort the following figures from smallest to largest:

2,150 (Correct answer)
405
10,000
99
450

Correct answer: 2,150

To sort the figures from smallest to largest, we arrange them in ascending order: 99, 405, 450, 2,150, 10,000. In this sorted list, 2,150 is the fourth number. The question implicitly asks for one specific number from the sorted list, and 2,150 occupies that position.

Question 5: Make use of your Magic Nines technique to find a solution. 9 x 6 is what?

56
15
54 (Correct answer)
72

Correct answer: 54

To solve 9 x 6, one can use basic multiplication facts. The product of 9 and 6 is 54. The 'Magic Nines technique' is a mnemonic device, often a finger trick, that helps visualize this product, where putting down the 6th finger leaves 5 fingers to the left (tens) and 4 fingers to the right (ones), resulting in 54.

Question 6: Write the solution to the following issue on paper: 21 x 5 =?

105 (Correct answer)
26
100
110

Correct answer: 105

To solve 21 x 5, you can break down the multiplication. Multiply 20 by 5 to get 100, and then multiply 1 by 5 to get 5. Adding these results together (100 + 5) gives you the final product of 105. This demonstrates the distributive property of multiplication.

Question 7: What would the problem look like if the long hand was on the number six and each number was worth five minutes?

6 x 5 (Correct answer)
6 + 5
5 x 50
30 x 5

Correct answer: 6 x 5

On a clock face, the long hand (minute hand) pointing to a number indicates a certain number of minutes past the hour. Since each number on the clock represents 5 minutes, and the hand is on the number six, the total minutes would be calculated by multiplying the number six by five. This represents 6 groups of 5 minutes.
