Question

find reduced form of ratio of quantity to quantity 7 min 20 sec ,5 min 6 sec​

Answer 1

7 min 20 sec = 420 + 20 = 440 second

5 min 6 sec = 300 + 6 = 306 second

440 = 2 × 2 × 2 × 5 × 11

306 = 2 × 3 × 3 × 3 × 17

HCF = 2

Required ratio = (440 /2) /(306/2)

= 220 / 153

= 220 : 153

Answer 2

Answer:

220 : 153

Step-by-step explanation:

7 mins 20 secs = 420 + 220 = 440 secs

5 mins 6 secs = 300 + 6 = 306 secs

440 = 2 × 2 × 2 × 5 × 11

306 = 2 × 3 × 3 × 17

HCF = 2 × 2 = 4

440/306 = (440÷2)/(306÷2)

= 220/153

= 220 : 153
