Question

draw a line segment of length 7.2cm and divide it in the ratio 5:3.Measure the two parts.

Answer 1

line = 7.2 cm.

consider 5:3 as 5x and 3x.

5x + 3x = 7.2

8x = 7.2

x = 7.2/8

x = 0.9

therefore =

                      5x = 5 * 0.9 = 4.5

                      3x = 3 * 0.9 = 2.7

therefore two parts of line are 4.5 and 2.7.

Answer 2

hey here is your answer...
the answer is given in the picture...☝☝
the measure of those two parts is...

7.2÷8=0.9
:.0.9×5=4.5cm___(1)

and..

0.9×3=2.7cm____(2)

are the measures of given two parts..

hope it helps you....
