The average time it takes a computer to execute one instruction is measured in picoseconds. There are 3.6 × 10^15 picoseconds per hour. What fraction of a second is a picosecond?

Work Shown:

1 minute = 60 seconds

60 minutes = 60*60 = 3600 seconds

1 hour = 3600 seconds

1 hour = 3.6 * 10^15 picoseconds

3600 seconds = 3.6 * 10^15 picoseconds

3600/(3.6 * 10^15) seconds = (3.6 * 10^15)/(3.6 * 10^15) picoseconds

(3.6 * 10^3)/(3.6 * 10^15) seconds = 1 picosecond

(3.6/3.6) * 10^(3-15) seconds = 1 picosecond

1 * 10^(-12) seconds = 1 picosecond

1/(10^12) seconds = 1 picosecond

1/(1,000,000,000,000) seconds = 1 picosecond

one trillionth of a second = 1 picosecond

side note:

we can go from

1/(1,000,000,000,000) seconds = 1 picosecond

to

1 second = 1,000,000,000,000 picoseconds

after multiplying both sides by 1,000,000,000,000

The number 1,000,000,000,000 is read out as "one trillion". The number of zeros (12) is due to the exponent of 12 in 10^12.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
