You can change the denominator to 10 which will get you to 55/10 + 4/10. You can add these two together to get 59/10
This shows the multiplication between 3 and 23. So your word problem will have to show that. Jean buys three packs of gum. Each pack has 23 pieces. How many pieces of gum does Jean have in total? :)
The expression would look like this: 2(3+x)
Hope this helps :)
