To write nine tenths as a decimal, it looks like this: .9
blank = representation.
When you write the decimal number '7' in Base-2 (binary), you write '0111'.
0.059 is a decimal.
2.45 is a decimal.
A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So the required decimal representation is 17100, exactly as in the question.
120
62% of 17100 is 17100 x 62/100 = 10602
17100
17100
It is 10602
17100 = 17100/1 = 17100/1 × 10/10 = 171000/10 = 17100/1 × 10²/10² = 1710000/100 = 17100/1 × 10³/10³ = 17100000/1000 ... = 17100/1 × 10ⁿ/10ⁿ There is no upper limit to this sequence: n = 0, 1, 2, 3, .... These numbers can be put in a one-to-one relationship with the counting numbers 1, 2, 3, ... The counting numbers can also be put in a one-to-one relationship with the whole numbers Therefore the sequence of fractions can be put in a one-to-one relationship with the whole numbers. Therefore the fraction of whole numbers which are in the sequence is 1. ----------- Let's try another approach: As 10 to some power is positive, there is no way we can change a negative number to make it positive by dividing by 10 to some power, therefore the solution numbers are all positive. As negative whole numbers make up half of the whole numbers, the fraction of whole numbers which are equivalent to 17100 when divided by a power of 10 is at most ½. The fraction of the ½ of the whole numbers which are positive can now be considered: After the nth whole number has been found which matches the criteria that is it equivalent to 17100 when it is divided by a power of 10, in total there are n numbers matching out of a total of 17100 × 10ⁿ⁻³ numbers (the value of the nth number); thus: The first number which meets the criteria is 171/10⁻² → the fraction is 1/171 The second number to meet the criteria is 1710/10⁻¹ → the fraction is 2/1710 The third number to meet the criteria is 17100/10⁰ → the fraction is 3/17100 The fourth number to match the criteria is 171000/10 → the fraction is 4/171000 The fifth number to match the criteria is 1710000/10²→ the fraction is 5/1710000 → For the nth match, the fraction is: n/(17100 × 10ⁿ⁻³) = (1/17100) × n/10ⁿ⁻³ This gives us a sequence of fractions: 1/17100 × 1/10⁻², 1/17100 × 2/10⁻¹, 1/17100 × 3/10⁰, 1/17100 × 4/10¹, 1/17100 × 5/10², ... = 100000/17100000, 20000/17100000, 3000/17100000, 400/17100000, 35/17100000, 6/17100000, .... Consider terms n and n+1: U{n} = (1/17100) × n/10ⁿ⁻³ = (1/17100) × 10 × n/10ⁿ⁻² U{n+1} = (1/17100) × (n+1)/10ⁿ⁻² U{n} - U{n+1} = (1/17100) × 10 × n/10ⁿ⁻² - (1/17100) × (n+1)/10ⁿ⁻² = (10n - (n+1))/(17100 × 10ⁿ⁻²) = (9n - 1)/(17100 × 10ⁿ⁻²) As n ≥ 1, 9n - 1 ≥ 9×1 - 1 = 8 → term n - term n+1 ≥ 8 > 0 → term n is larger than term n+1 for all n ≥ 1 Each of these terms is less than 1, and each term of the sequence is smaller than the previous one and so as n increases the value of the each term (the fraction of whole numbers which meet the criteria) tends towards 0. → The fraction of all whole numbers which equate to 17100 when divided by a power of 10 is as near enough to zero as make no odds. ie the fraction is so small it is effectively none of the whole numbers. ----------------------- This is a problem of dealing with the infinite.
how do you write a this as decimal 9265
you divide the numerator by the denominator on you will get a decimal and you write it 00.00 that is a decimal
You first write the integer part, then write the decimal point and then the fractional part in decimal form.
160 is a decimal. You can write 160.0 if you want to.
