First Left hand of decimal
1*(2^4 )+ 0*(2^3 )+ 0*(2^2) + 1*(2^1) + 1*(2^0) = 19
Now right side of decimal is,
0*(2^-1) + 1 *(2 ^-2) = 1/4 = .25
So 19.25 is required decimal

Why is money written in decimal form?
Money is written in decimal for easier computation. Imagine if money is in fraction form, it will be hard for us to compute.
How do you compute scientific notation?
To convert a number to scientific notation: · If the number has no decimal point, then add one at the end. · Then move the decimal point to just after the first digit while counting the number of places you have moved it. · The mantissa of the new number, formed after moving the decimal point is a. · If the original number is negative, then so is a. · The number of places to the left that the decimal point was moved is b. If it was moved to the right, then b is negative. For example: 23045.06 becomes 2.304506*10^4 -23045.06 becomes -2.304506*10^4 0.00023004 becomes 2.3004*10^-4
Can a decimal number be a whole number?
No. A whole number is a number with no fractional (decimal) part. Therefore a decimal number can not be a whole number. Another view: 35.0 is a whole number AND a decimal. The fact that a number is a decimal does not automatically require it to have a fractional part. Even 35 is a decimal number (without a decimal point).
What is 27.9 as a decimal?
27.9 IS a decimal number. You can tell it is a decimal number because it has a decimal point (.).

How do you compute atomic number?
The atomic number of any element is the number of protons in the nucleus of that element, which you can easily find in the periodic table of elements. You don't have to compute anything.
How do you find 2 and half percent of a number?
To find 2 1/2% of a number, multiply the given number by the 0.025 which is the decimal equivalent of 2 1/2. Example: Compute for 2 1/2 of 200. = 0.025 * 200 = 5

How many significant figures do you use for logarithms for example ln 3.02?
The number of significant figures after the decimal place matches the number of significant figures before the computation of the logarithm. Thus ln(3.02) would compute to 1.105. Three significant figures to four significant figures (3, after the decimal place).
