Describe how the two numbers are alike. Describe how they are different.
Answer: The only difference is two numbers are place values.
In Mathematics, place value charts help us to make sure that the digits are in the correct places. To identify the positional values of numbers accurately, first, write the digits in the place value chart and then write the numbers in the usual and the standard form.

Place value: Place value in Maths describes the position or place of a digit in a number. Each digit has a place in a number. When we represent the number in general form, the position of each digit will be expanded. Those positions start from a unit place or we also call it one’s position. The order of place value of digits of a number of right to left is units, tens, hundreds, thousands, ten thousand, a hundred thousand, and so on.
There are 2 blocks of hundreds it is equivalent to 200 so it was 2*100=200.
There are 4 blocks of tens it is equivalent to 10 so it was 4*10=40
There are 7 blocks of ones it is equivalent to 1 so it was 7*1=7
