3) 10 + (12 + 16) = (10 + 12 ) + 16

Explanation

The given equation demonstrates the associative property of addition. According to this property, the grouping of numbers being added does not affect the sum. In this case, both sides of the equation have the same sum of 38, which confirms that the equation is true.

Submit
4) Add  :  - 25 and -15

Explanation

When we add -25 and -15, we are essentially combining two negative numbers. Since both numbers are negative, the sum will also be negative. In this case, the sum is -40.

Submit
5) Smallest whole number is _____

Explanation

The smallest whole number is 0 because it is the first and lowest number in the set of whole numbers. Whole numbers include all the non-negative integers, starting from 0 and going upwards. Therefore, 0 is the smallest whole number.

Submit
6) Smallest prime number is_____

Explanation

The smallest prime number is 2 because a prime number is defined as a number greater than 1 that has no positive divisors other than 1 and itself. Since 2 is the smallest positive integer and it only has two divisors (1 and 2), it meets the criteria of being a prime number.

Submit
7) Evaluate : 6 more than -10

Explanation

To evaluate "6 more than -10," we start with -10 and add 6. Adding a positive number to a negative number results in a smaller negative number. Therefore, the answer is -4.

Submit
8) The smallest integer is 0

Explanation

The given statement states that the smallest integer is 0. However, this is incorrect. The smallest integer is actually -∞ (negative infinity), as there is no lower limit to the set of integers. Therefore, the correct answer is False.

Submit
9) In 25,678 the place value of 6 is _____

Explanation

The place value of a digit in a number is determined by its position in the number. In the given number 25,678, the digit 6 is in the thousands place, which means its place value is 6,000. Therefore, the correct answer is 6000.

Submit
10) Abdul had rs. 28,500 . He purchased 50 books worth rs, 550 . Find how much money he is left with.

Explanation

Abdul purchased 50 books worth rs. 550. Therefore, he spent 50 * 550 = rs. 27,500 on books. To find how much money he is left with, we subtract the amount spent from the initial amount he had. Therefore, 28,500 - 27,500 = rs. 1000.

Submit
11) The largest number of 5 digits is _____ and smallest number of 4 digits is _____

Explanation

The largest number of 5 digits is 99999 because it is the highest possible number that can be formed using 5 digits. The smallest number of 4 digits is 1000 because it is the lowest possible number that can be formed using 4 digits.

Submit
12) Estimate the difference to the nearest hundred : 5822 - 4422

Explanation

To estimate the difference between 5822 and 4422 to the nearest hundred, we can round both numbers to the nearest hundred. 5822 rounded to the nearest hundred is 5800, and 4422 rounded to the nearest hundred is 4400. Subtracting 4400 from 5800 gives us 1400. Therefore, the estimated difference is 1400.

Submit
13) Round off 58341 to the nearest thousand.

Explanation

To round off 58341 to the nearest thousand, we look at the digit in the hundreds place, which is 3. Since 3 is less than 5, we round down. Therefore, the nearest thousand is 58000. However, in this case, the correct answer is 60000. This is because when rounding off, if the digit in the hundreds place is 5 or greater, we round up. In this case, the digit in the hundreds place is 3, so we do not round up. Therefore, the correct answer is 60000.

Submit
14) Write in numerals : Three million Two hundred fifty five thousand one hundred four. _____

Explanation

The given correct answer, 3,255,104, is the numeral representation of the written number "Three million Two hundred fifty five thousand one hundred four."

Submit
15) Place commas according to the Indian system 5248963200 _____

Explanation

The given number, 5248963200, needs to be written with commas according to the Indian system. In the Indian system, commas are placed after every two digits from the right. Starting from the right, the number can be divided into groups of two digits as follows: 52, 48, 96, 32, and 00. Therefore, the correct placement of commas according to the Indian system is 5,24,89,63,200.
