(a) 5 sec of 1 minute
(b) 17 of 68

Answer 1

SOLUTION :

(a) 5 sec of 1 minute

We know that 1 minute = 60 seconds

So,

Out of 60 seconds, 5 seconds is written as

$= \frac{5}{60}$

Converting into percentage

= $= \frac{5}{60} \times 100$ %

= 8.33 %

Hence,

5 seconds is 8.33% of 1 minute

= 25%

Hence,

17 is 25% of 68
