To change any percent into a decimal, multiply the percent by 0.01 (exact); therefore 83 percent = 0.83
The exact value of giga, in the context of metric prefices is 10^9 = 1,000,000,000 (1 billion). In the context of computer technology, it is 2^30 = 1,073,741,824.
It is impossible to express 8/17 as an exact decimal as it has 16 digits that recur: 8/17 = 0.47058823529411764705882352941176...
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. It may or may not contain a fractional part. If not, the decimal representation does not require a decimal point. So the decimal for 1 mega is 1 mega. If you want it as a decimal fraction of some other quantity then you need to specify that second quantity.
Because - Hex is an exact multiple of binary - whereas decimal numbers need to be converted from base 10 to base 2.
(f) What is the exact value (in decimal) of giga?
-2.875 is an exact decimal
That is correct.
There is no such example. If you cannot use an exact fraction then there will not be an exact decimal that you can use instead. And, if you are using an approximate decimal, you could use an approximate fraction instead.
I have the same exact question:(
6/19 has no exact decimal equivalent. It is approximately .3157894.
1048677
That is the decimal form. 2/25ths is the fraction form. Approximately. 83/1,000ths to be exact.
-21.6
15/64 = 0.234375 (exact)
The exact square root is √6 or 60.5. It is an irrational number and so cannot be expressed in exact form as a decimal number.
3.1415926536 is to 10 places but not exact. The only exact value of pi is pi itself. So any exact answer involving pi would include pi in the answer.
