Question

Divide seg AB of length 7 cm into ratio 3:2​

Answer 1

Step-by-step explanation:

Śtep 1 - draw Ray AC making an acute angel with AB.

Step 2- starting with A, mark of 5 points

C1, C2, C3, C4, C5 at equal distance from the point A.

Step 3- Join C5 and B.

Step 4- Through C2 (I. e the second point), draw C2 and D parallel to C5 B meeting AB in D.

Then D is required points, which divides AB segment into 2:3 part.

Answer 2

Given: A segment AB is of length 7 cm.

To find: 3:2 ratio of AB

Solution:

• When a line is divided in a ratio of 3:2, it means that it is being divided into two parts such that one of the them three times of a value and the second part is two times a particular value.
• In order to solve, the ratios are first added and this gives the value,

        $3 + 2 = 5$

• To find the value of the first part, the following calculations are done,

        $\frac{3}{5} * 7cm = 4.2cm$

• Similarly, for the second part,

        $\frac{2}{5} * 7cm = 2.8cm$

Therefore, 7 cm divided into ratio the 3:2 is 4.2 cm and 2.8 cm.
