Please explain

f=1/T so that 1/1.25micro sec = 0.8Mhz

By the formula of frequency we can find the frequency of clock
waveform.
Time period(t)is given of that waveform is=1.25microseconds
f=1/t
Where T is the time taken by the clock waveform.
f=(1/1.25)
And f=0.8mhz

1.25us = 125x10^-8 sec.
Thus, 1/T = f.

Hence, f = 1/125x10^-8 sec.
f = 800kHz = 0.8MHz.

Just 1/1.25 * 10^-6 = 10^6 * 100/ 125 = 0.8 MHz.

= 100/125*10^-8.
= (4/5)*10^6.
= (0.8)*10^6.

= (0.8)*10^6.
= 8 MHZ.
