Sum 3537 + 3884 to nearest tens is
-
1000
-
7400
-
7420
-
7440
Correct Answer
A. 7420Explanation
To find the sum of 3537 and 3884 to the nearest tens, we round each number to the nearest tens and then add them together. Rounding 3537 to the nearest tens gives us 3540, and rounding 3884 to the nearest tens gives us 3880. Adding these rounded numbers together gives us 7420, which is the nearest tens value for the sum of 3537 + 3884.Rate this question:

In the international system of numeration, we use commas to separate the periods of thousands, millions, billions, etc. The number 235,006 is read as "two hundred thirty-five thousand and six". The word "and" is used to separate the hundreds place from the tens and units place within a period.Rate this question:

Correct Answer
A. 400Explanation
To find the sum of 267 + 132 to the nearest ten, we first add the two numbers which gives us 399. Since 399 is closer to 400 than to any other multiple of ten, the sum rounded to the nearest ten is 400.Rate this question:

None of the above
Correct Answer
A. 2Explanation
The only even prime number is 2. This is because a prime number is defined as a number greater than 1 that has no positive divisors other than 1 and itself. While all other even numbers can be divided by 2, making them not prime, 2 can only be divided by 1 and 2, making it the only even prime number.Rate this question:

The tickets sold for the semi-final IPL match were 9872, whereas 10050 tickets were sold during the finals. How many more tickets, estimated to the nearest tens, were sold during the finals?
-
160
-
170
-
180
-
190
Correct Answer
A. 180Explanation
During the finals, 10050 tickets were sold, whereas for the semi-final match, only 9872 tickets were sold. To find out how many more tickets were sold during the finals, we subtract the number of tickets sold for the semi-finals from the number of tickets sold during the finals. Therefore, 10050 - 9872 = 178. Since we need to estimate to the nearest tens, the answer would be 180.Rate this question:

Estimated value of 467 to nearest thousand is
-
Zero
-
400
-
470
-
1000
Correct Answer
A. ZeroExplanation
The estimated value of 467 to the nearest thousand is zero because when rounding to the nearest thousand, any number below 500 will be rounded down to zero. In this case, 467 is less than 500, so it gets rounded down to zero.Rate this question:

-
1
-
10
-
100
-
1000
Correct Answer
A. 100Explanation
To solve the equation, we can substitute the given values into the equation and solve for the missing value. By substituting 100 for the missing value, we get 15 * 1000 + 7 * 100 + 6 * 10 = 15760. Simplifying the equation, we get 15000 + 700 + 60 = 15760. Combining like terms, we get 15760 = 15760, which is a true statement. Therefore, the missing value must be 100.Rate this question:

Estimated the value of the product of 108 and 12.
-
1000
-
1500
-
1700
-
2000
Correct Answer
A. 1000Explanation
The product of 108 and 12 can be estimated by rounding both numbers to the nearest ten. 108 rounds to 110 and 12 rounds to 10. Multiplying these rounded numbers gives us an estimate of 1100. However, since we rounded up for both numbers, the actual product will be slightly less than 1100. The closest option is 1000, which is the correct answer.Rate this question:

1 billion = ______ million
-
10
-
100
-
1000
-
10000
Correct Answer
A. 1000Explanation
1 billion is equal to 1000 million. This is because:
1 billion = 1,000,000,000 (in numbers)
1 million = 1,000,000
When you divide 1 billion by 1 million, you get:
1,000,000,000 ÷ 1,000,000 = 1000
So, 1 billion is equal to 1000 million.Rate this question:

-
100
-
200
-
250
-
300
Correct Answer
A. 200Explanation
The sum of 178 and 69 is 247, and when rounded to the nearest hundred, it is 200 (since 247 is closer to 200 than to 300). Here's the correct response:
The correct answer is: 200.
Explanation: The sum of 178 and 69 is:
178+69=247
When rounding 247 to the nearest hundred, since 247 is less than 250, we round down to 200.Rate this question:

Rita has a ribbon of length 2070 mm. Sita has a ribbon whose length is 1232 mm shorter than Rita's ribbon. What is the approximate length of Sita's ribbon when rounded to the nearest hundred (in millimeters)?
-
500
-
1000
-
800
-
2000
Correct Answer
A. 800Explanation
To find the approximate length of Sita's ribbon, we need to subtract 1232 mm from Rita's ribbon length and then round the result to the nearest hundred.
Rita's ribbon length = 2070 mm Sita's ribbon length = Rita's ribbon length - 1232 mm
Sita's ribbon length ≈ 2070 mm - 1232 mm Sita's ribbon length ≈ 838 mm
When rounded to the nearest hundred, Sita's ribbon length is approximately 800 mm.Rate this question:
