How would the fraction 7962 over 10,000 be written in scientific notation

If you convert it to a scientific notation it should be written out

7.962*10^-1.

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. The sign of the exponent will depend on the direction you are moving the decimal.

I hope this helps.
