I have a question similar to the original one, in regards to how to say a particular fraction when it comes up with my students. The Progression documents have a number of examples of fractions in which the numerator is an addition or multiplication expressions, such as 5 + 4/9 (5 + 4 as a numerator and 9 as a denominator). How would this be read exactly? If I were to say 5 + 4 ninths, it would seem to be indicating a mixed number. Would I repeat the word “ninths”, reading it as five-ninths plus four-ninths, as it were two different fractions?
Thank you for your help.
