Question

Pls tell the answer plus explanation of how and why

Answer 1

Explanation:

Let the length of one grey rod be g, black rod be b and white rod be w.

Given,

$3g = 2b$

, meaning length of three grey rods is equal to length of two black rods.

It is also given that

$3g + 2b = w$

, meaning sum of lengths of three grey rods and two black rods is equal to length of one white rod.

Since we know that 3g = 2b,

$3g + 2b = 3g + 3g = w$

$6g = w$

$g = \frac{1}{6} w$

Hence, the length of grey rod is one sixth the length of the white rod.

Answer: 1/6
