Question

how will you divide a line segment AB =4.9 cm in the ratio 3:4.

Answer 1

let the ratio be 3x:4x.
now, 3x+4x=4.9cm
7x=4.9cm
x= 4.9/7
x= 0.7 cm
now we have x = 0.7 cm
now 3x=3×0.7 = 2.1 cm
and , 4x=4×0.7=2.8cm

Answer 2

let the ratio be 3x:4x ,
now, 3x+4x=4.9 cm
7x =4.9
x =4.9/7
x =0.7
putting the value of x
3x/4x =3*0.7/4*0.7
=2.1/2.8
the ratio is 2.1:2.8

I hope it's helps you
