Answer 1

Answer:

(i)75%

(ii)33.3%

(iii)1.49%

(iv)1.66%

Step-by-step explanation:

(i) 1 hour = 60 minutes

percentage of 45minutes in 60minutes

= 45/60 x 100

= 4500/60

= 75%

(ii) 1 year = 12 months

percentage of 4 months in 12 months

= 4/12 x 100

= 100/3

= 33.3%

(iii) 5cm,335cm

percentage of 5cm in 335cm

= 5/335 x 100

=500/335

= 1.49%

(iv) percentage of 60° in 360°

= 60/360 x 100

= 600/360

= 1.66%
