Solution

## To take the ratio we will convert both the quantity in same units.(i) Rs. 1 =100 paise [To convert rupees to paise, multiply rupees by 100]∴ 75 paise : Rs. 3 = 75:300=1:4(ii) 35 minutes :45 minutes =7:9(iii) 1 kg=1000 gm[To convert kg to gm, we have to multiply by 100]8 kg:400 gm=8000:400=20:1 (iv) 1 Hour =60 minutes [To convert hour to minutes, we have to multiply hour by 60] 48 minutes :1 hour =48:60=4:5(v) 1 metre =100 cm [To convert metre to cm, we have to multiply by metre to 100]2 metres :35 cm=200:35=40:7(vi) 1 minute =60 seconds.35 minutes to 45 seconds=35×60:45=140:3(vii) 1 dozen =12 1 score =20 or 3 score =3×20=60 2 dozen: 3 scores =24:60=2:5.(viii) 1 week =7 days [To convert week in days multiply by 7] 3 weeks :3 days =21:3=7:1(ix) 1 hour =60 minutes 2 hour 40 minutes =2×60+40=160 48 min :2 hour 40 minutes =48:160=3:10 (x) 1 meter =100 cm 3 m 5 cm=3×100+5=305 cm 305 minutes :35 minutes =61:7  Suggest Corrections  1      Similar questions
