__________________________________________

(a)
What Percent is 5 sec of One minute


we have,
1 Minute = 60 Seconds

We need to find,
What Percent is 5sec of 60 Sec


60 Sec ----- 100%
5 Sec ------- ? % (Say x)

Cross Multiply

60×x = 5×100
=>12 x = 100
=> x = $\frac{100}{12}$
=> x = $\frac{25}{3}$
=> x = $8\frac{1}{3}$ %

•°• Required Percent = $8\frac{1}{3} = 8.33$ %

Therefore,
5 seconds is 8.33% of one minute.

------------------------------------------------------------

(b)

What Percent is 17 of 68

68 ---- 100%
17 ------ ? % (Say x)

Cross Multiply

68×x = 17×100
=> 4x = 100
=> x = 25%


Therefore,
17 is 25% of 68
