Question

divide 7 km 500 m in the ratio 8 is to 7

Answer 1

7km 500m=7500
let the parts be 8x and 7x
8x+7x=7500
15x=7500
x=7500/15=500
Ist part=7x=3500m=3km 500m
IInd part=8x=4000m=4 km

Answer 2

ratio 8:7
sum of ratio =15

7 km 500 m= (7×1000)+500 m =7500 m

for 8=7500×8/15 m
       =4000 m = 4 km

for 7=7500×7/15 m
       =3500 m =3.5 km
