As I am preparing for an English exam, I have questions about what I read here and then so I really appreciate if you can tell me if this sentence is correct in terms of its grammar. To be more specific, I was confused that why there is no comma after "evident" but even after putting comma in between, it is still quite vague with a second language learner like me.
A similar growth in the figure for children was evident reaching 25% in 2007 and around 24% in the final year.
Also, should I put comma after "items" and "expenditure"?
Turkey spent most on these items at just 4% of their national expenditure which is around double that of Spain (1.8%)
