How to calculate real GDP with nominal GDP and inflation rate

Real GDP= nominal GDP÷ GDP deflator (refers to the index whose base period is 100).

Nominal GDP = real GDP × GDP deflator

As for the relationship between nominal GDP growth rate and real GDP growth rate, it is

Nominal GDP growth rate =[( 1+ real GDP growth rate) x( 1+ local deflator growth rate) x 100%]- 1.
