There are 39 books in the Old Testament an 27 books in the New Testament. Write a ratio in lowest terms to compare the number of books in the Old Testament to the number in the New Testament.

I don't quite remember how to do ratios, could someone please help?

A ratio is a fraction on one number divided by the other. In this case,

Old/New = 39/27 = 13/9

I believe it's 13:9
I think u will have 2 divide both of them so that u get 13 as numerator and 9 as denominator.They can't be further divided.Then write them in the ratio form.u will get 13:9
I learnt it long before.So I am not sure.Just try

thanks alot!
