ROUNDING OFF NUMBERS

Answers with Step-by-step explanation:

1.) 47 round off to the nearest tens

When you round off 47 to the nearest tens, the answer is 50. When we round off numbers, we always look at the digit to its right. When its value is 0 to 4, we will round down the number but if when its value is 5 to 9, we will round up the number. Since 7 is between 5 and 9, we can decide to round up 47 and add 1 to its tens digit.

2.) 63 round off to the nearest tens

When you round off 63 to the nearest tens, the answer is 60. The number on the tens digit is 6 and the number to its right is 3. Since 3 is between 0 and 4, we can decide to round down 63 and remain its tens digit.

3.) 437 round off to the nearest hundreds

When you round off 437 to the nearest hundred, the answer is 400. The number on the hundreds digit is 4 and the number to its right is 3. Since 3 is between 0 and 4, we can decide to round down 437 and remain its hundreds digit.

4.) 582 round off to the nearest hundreds

When you round off 582 to the nearest hundreds, the answer is 600. The number on the hundreds digit is 5 and the number to its right is 8. Since 8 is between 5 and 9, we can decide to round up 582 and add 1 to its hundreds digit.

5.) 7,615 round off to the nearest thousands

When you round off 7,615 to the nearest thousands, the answer is 8,000. The number on the thousands digit is 7 and the number to its right is 6. Since 6 is between 5 and 9, we can decide to round up 7,615 and add 1 to its thousands digit.

1.) 500 x 20 = 10,000

2.) 400 x 50 = 20,000

3.) 600 x 40 = 24,000

4.) 3,000 x 200 = 600,000

5.) 2,000 x 600 = 1,200,000

In obtaining the products of this numbers ending in zeros, just simply multiply their nonzero digits and whatever the product that you obtained, just add the total number of zeros present in two factors. For example, we have 500 multiplied by 20. The nonzero digits are 5 and 2 . We all know that 5 x 2 is 10. Then, we will add the zeros to the answer. We have a total of 3 zeros so thee final answer is 10,000.
