Question

state the procedure to write the number in a decimal notation​

Answer 1

Notice that the the decimal place is moved to the left the same number of digits as number of zeros in the denominator. To read decimal numbers remember that from left to right the digits to the right of the decimal point are: Tenths, Hundredths, Thousandths, Ten-Thousandths, etc.

To change a number from scientific notation to standard form, move the decimal point to the left (if the exponent of ten is a negative number), or to the right (if the exponent is positive). You should move the point as many times as the exponent indicates. Do not write the power of ten anymore.

hope this helps a bit!
