1. You have to know the base of the original number. 2. If the base of the original number is base 10, then you don't need to convert it to decimal because the original number is already a decimal number. This means the decimal numbering system is base 10 (i.e. it has 10 base digits-->0-9) 3. If the base of the original number is different than base 10, then you will need to use a mathematical conversion method (or a computer program/calculator) to convert the original number to decimal. For example: If the original number 1011 is a base 2 (binary) number, then you would use the following conversion method to convert it from base 2 to base 10: 1 * 2^0 = 1 * 1 = 1 1 * 2^1 = 1 * 2 = 2 0 * 2^2 = 0 * 4 = 0 1 * 2^3 = 1 * 8 = 8 Now add the right most column of numbers together (e.g.: 1+2+0+8=11). 11 is the decimal (base 10) equivalent to the original base 2 number 1011. Similar methods can be used to convert from other base numbering systems to decimal (e.g. base 5 to base 10)
43 base 5 = (4 * 5^1) + (3 * 5^0) = 20 + 3 = 23
4 is 4 in hexadecimal of decimal.
4 and 3/10 becomes the improper fraction 43/10. You multiply 10 by 4 and add 3. The decimal is 4.3.
To subtract 11 in base 2 from 100 in base 2, you first convert both numbers to decimal. 100 in base 2 is equal to 4 in decimal (12^2 + 02^1 + 02^0). Similarly, 11 in base 2 is equal to 3 in decimal (12^1 + 12^0). Subtracting 3 from 4 in decimal gives you 1 in decimal, which is equal to 1 in binary (12^0). Therefore, 100 in base 2 minus 11 in base 2 equals 1 in base 2.

4 and 4/10 or 4 and 2/5
Interpret the number as 76000.0. Then, shift 4 decimal places to the left, so the exponent for base 10 is 4. Therefore, we obtain: 7.6 x 104.
0.4 is already a decimal. If you wanted it as a fraction it would be 4/10 or simplified to be 2/5.
Convert the ratio to fraction first, then convert the fraction to decimal. Example: ratio = 3 : 4 3 : 4 = 3/4 = 0.75
Note that the number is the same as 36507.0. Shift 4 decimal places to the left, so the exponent for base 10 is 4. Therefore, 36507 in scientific notation is 3.6507 x 104.
43 base 5 = (4 * 5^1) + (3 * 5^0) = 20 + 3 = 23
110100 (base 2) = 32+16+4 = 52 (base 10)
Move 4 decimal places to the right from the starting position to get 1.27 x 10-4
in the following decimal: .4567 the "4" is in the one-tenth spot.0.1
4/11 is a repeating decimal.
4 is 4 in hexadecimal of decimal.
