Answer 1

Answer:

hiiii

your answer is here !

Step-by-step explanation:

(a) Required ratio = 64 cm/4.8 m

= 64 cm/(4.8 × 100) cm

= 64 cm/480m

= 64/480

= 2/15

= 2 : 15

(b) Required ratio = 36 minutes/36 seconds

= (36 × 60 seconds)/(36 seconds)

= 60/1

= 60 ∶ 1

(c) Required ratio = (30 dozen)/(2 hundred)

= (30 × 12)/(2 × 100 )

= 3/10

= 3 ∶ 10
