Question

Divide a line segment of length 7.5 cm in the ratio 2:1 . Measure the two parts.

Answer 1

Since we have to divide the line segment in the ratio 2:1,

first divide 7.5 cm by 3(since 2+1=3)

So it will give u 2.5cm

Now just multiply the above value with the corresponding ratio.

ie 2×2.5:1×2.5

= 5cm:2.5cm

Hope it helped u ☺️

Answer 2

Answer:

Concept: For two divided parts, the sum of the ratio can be expressed as the length of the line segment.

Given: Length of line segment=7.5cm, divided in ratio 2:1

To find: The measure of two parts.

Step-by-step explanation:

$2x+1x=7.5$

$3x=7.5$

$x=2.5$

the measure of parts are

1x=1×2.5=2.5 cm

2x=2×2.5=5 cm
