When a 3 digit number is rounded to the nearest ten and to the nearest hundred, the answer is the same. What is one possible number that fits this rule?
Answers
The one possible number that fits this rule is 495
Step-by-step explanation:
Let us revise how we can round a number
1. When we round a number to the nearest ten we look to the one
digit if its 5 or greater than 5 we add the ten digit by 1 and put the
one digit 0, if the one digit less than 5 we keep the ten digit as it
and put the ones digit 0
2. When we round a number to the nearest hundred we look to the
ten digit if its 5 or greater than 5 we add the hundred digit by 1 and
put the ten and one digits 0, if the ten digit less than 5 we keep the
hundred digit as it and put the ten and one digits 0
Examples:
If 256 rounded to the nearest ten, then it will be 260
and if rounded to the nearest hundred, then it will be 300
If 543 rounded to the nearest ten, then it will be 540
and if rounded to the nearest hundred, then it will be 500
Now let us solve the problem
We are looking for 3 digit number when rounded to the nearest ten
and to the nearest hundred give the same answer
∴ Its unit digit must be 5 or greater than 5 to add ten digit by 1
∴ Its ten digit must be 9 because when we add 9 by 1 it will be 10
and that mean the hundred digit will added by 1
- If The number is 495
∵ Its unit digit is 5
∴ When we round it to the nearest ten we will add the ten digit 9 by 1
∴ The ten digit will be 10 then we will add hundred digit by 1
∴ The hundred digit is 5 , ten digit is 0 and we will put the one digit 0
∴ The number after rounded to the nearest ten is 500
∵ When we round it to the nearest hundred we will look to the ten digit
∵ Its ten digit is 9
∴ We will add the hundred digit 4 by 1 and put the ten and one digits 0
∴ The number after rounded to the nearest hundred is 500
The one possible number that fits this rule is 495

Given -
50 times 4 =200
Find out the values of 500 times 400.
To prove
As given in the question
50 times 4 =200
i.e the above also written in the form as follows.
50 × 4 = 200
Now find out for 500 times 400.
500 times 400 is also written in the form as follows .
500 × 400 = 200000
Therefore the 500 times 400 is 200000.
Hence proved
To find 500 times 400 from 50 times 4 =200 : usecommutative, associative properties and place value
500 times 400
Further explanation
There are 3 properties in arithmetic operations that can be applied to arithmetic operations, namely: commutative, associative , and distributive properties
Commutative properties are mathematical operations of two numbers that are exchanged and produce the same results
a + b = b + a = c
a x b = b x a = c
this property applies to addition and multiplication operations.
Associative properties are mathematical operations of 3 numbers by grouping 2 numbers with parentheses and the location of the grouping is exchanged with the result that remains the same
(a + b) + c = a + (b + c) = d
(a × b) × c = a × (b × c) = d
Distributive properties are mathematical operations with 2 different arithmetic operations, by distributing numbers grouped in parentheses.
a × (b + c) = (a × b) + (a × c) = d
In the digit system, the value of a number depends on its place, or position, in the number.
Each digit is different place value.
the place value of the digits in a number: hundred thousands, ten thousands, one thousands, hundreds, tens, ones, decimal points, tenths, hundredths, thousandths, ten thousandths, hundred thousandths
From the task:
use the previous problem (50 times 4 = 200) to help solve 500 times 400.
50 times 4 = 200
in the form of arithmetic operations
50 x 4 = 200
or in place value
5 tens x 4 ones = 2 hundreds
we can use associative and commutative properties
so multiplication can be expressed in an interchangeable form because it has the same value
So to complete 500 x 400:
multiplying the whole numbers first then the zeros
The difference between first number operations and second number operations is the place value unit
500 x 400
= 5 hundreds x 4 hundreds
= 5 x100 x 4 x 100 (there are 4 times of 10)
= (5 x 4 x 10) x 10 x 10 x 10
⇒ (5 x 4 x 10) = from previous problem
= 200 x 10 x 10 x 10

The correct answer is A. -4.
When you subtract a negative, it is the same as adding a positive (the two negative signs cancel each other out). Therefore, we have:
-6 + 2 = -4
A. -4. when you subtract a negative you are actually adding so you would add 2 to -6 and end up with -4
