Answer 1

Length of each parts in ratio =2:3:4
Each=3x.,4x,2x
Total part=180
2x+3x+4x=180
9x=180
X=180/9
x=20
2x=40
3x=60
4x=80

Answer 2

Hey dear here is your answer!!!!!

___________________________

We have been asked to divide the given plank in the ratio 2:3:4

Each part of the plank can be expressed in the form of 2x, 3x and 4x.

According to question:-

2x + 3x + 4x = 180

9x = 180

x = $\frac{180}{9}$

x = 20cm

So, each part would be of length:-

1. 2(20) = 40 cm
2. 3(20) = 60 cm
3. 4(20) = 80 cm

So, the length of the parts would be 40, 60, 80 cm respectively !
