Question

find the ratio of first quantity to the second quantity in the reduced form 7 min 20 sec, 5 min 6 sec​

Answer 1

Answer:

7 min 20 sec = 420 + 20 = 440 second

5 min 6 sec = 300 + 6 306 second

440 = 2× 2 × 2 × 5 × 11

360 = 2 × 3 × 3 × 3 × 17

HCF - 2

Required ratio = (400/2) (306/2)

= 200 / 153

= 200 : 153
