Question

Find the third proportional to 1km 500m to 300m

Answer 1

hope it works ,the answer would be

1000:500::300;150

Answer 2

=> a = 1km 500m

1km = 1000m

so a = 1000 + 500 =1500


=> b = 300m

=> c be the third proportional


condition :-

a : b = b : c

1500 : 300 = 300 ; c

1500c = 300 × 300

1500c = 90000

c = 90000/1500

c = 60
