Question

If a line-segment AB of length 7.8 cm is divided in ratio 5:8 at point

P. What will be actual length of PB?​

Answer 1

Step-by-step explanation:

Let the length of ap be 5x and pb be 8x

A.T.Q. ,

5x+8x= 7.8

13x= 7.8

x= 7.8/13

x= 0.6

The value of x is 0.6

Then the value of ap 5x= 5× 0.6= 3.0cm

The value of pb 8x= 8× 0.6= 4.8cm

The actual value of pb is 4.8cm
