Step-by-step explanation:
Share 20pounds in the ratio 2:3
Total ratio=2+3=5
2/5×20=8
20-8=12
Sharing 20pounds in that ratio gives 8pounds:12pounds
Share 15cm in the ratio 1:3
Total ratio=1+4=4
¼×15=3.75
15-3.75=11.25
Sharing 15cm in that ratio gives 3.75:11.25

Step-by-step explanation:
Line Segment: Line segment is a portion of a line whose has two end points.
Given that point C is on the line segment
.
= 5x ,
= 4x and
= 4
C is the point of the line segment of
.
So we can write

Putting the values of
,
and 
5x=4x+ 4
⇒5x-4x= 4
⇒x=4
So we get the value of x.
To get the value of
, we need to put the value of x in the value of
.
Therefore,
= 5×4
=20
Therefore the required value of
is 20 units.
