Write 5/3 as a decimal. If necessary, use a bar to indicate which digit or group of digits repeats.
5/3 as a decimal is 1.66667, with the digit 6 repeating.
Suppose some computations were done on a calculator.
The result displayed was 9.596E25 for one computation.
The result displayed was 4E-36 for another computation.
Write these numbers in scientific notation.
9.596E25 in standard scientific notation is 9,596,000,000,000,000,000,000,000 or approximately 9.596 x 10^25.
4E-36 in standard scientific notation is 0.000000000000000000000000000000000004 or approximately 4 x 10^-36.
To convert a fraction to a decimal, you divide the numerator (the number on top) by the denominator (the number on the bottom).
In this case, the fraction is 5/3.
Dividing 5 by 3, we get 1.6666... (the 6s go on forever).
To indicate that the 6s repeat, we can write the decimal as 1.6 with a bar over the 6: 1.6̅.
