1. The problem statement, all variables and given/known data

I have a linear dielectric material. The electric field in the material is 38% less than a vacuum field with the same external sources. I need to find the susceptibility of the material?

2. Relevant equations

P=$$\chi(vacuum)$$ E

P=
$$\chi(material)$$ .62E

3. The attempt at a solution

i did the ratio of the 2 and i found
$$\chi(material)$$= 1.61

is this correct?
