Multiply the first fraction by the reciprocal of the second. That is, flip the second fraction over and then multiply the two.
It could be as little as just over zero (from a fraction of a second before noon to a fraction of a second after) to as much as 12 hours (from a fraction of a second after midnight to a fraction of a second after noon).
"Dividing Fractions is easy as pie, flip the second and multiply." Flip the second fraction, and multiply, and reduce.
write the unit as a fraction 25 feet per second
To divide a fraction by a fraction, multiply the first fraction by the reciprocal of the second one.

1 picosecond is one trillionth of a second, which can be represented as 1/1,000,000,000,000.
Because division by a number (the second fraction) is the same as multiplication by its reciprocal.
To divide a fraction by a fraction, multiply the first fraction by the reciprocal of the second one.
When dividing by a fraction, the second fraction (the divisor) is changed into its reciprocal by swapping the numerator and denominator over (turning it upside down) and then it is multiplied by the first number (fraction).
It is one billionths of a second.
Second
A nano-second is a fraction of 1 x 10-9 a second.
To divide a fraction by a second fraction, multiply the first fraction by the reciprocal of the second fraction. For example, 1/2 divided by 5/7 is the same as 1/2 times 7/5.
