Mia uses the following method to find :
“To find , I need to find the number of fourths in . I can make a model of , but I think it would be difficult to figure out the number of fourths in the model.
“I think the problem would be easier if both fractions had the same denominator. I can change the denominator of each fraction to 12 and rewrite the problem as .
“Now I can make a model of and then find the number of groups of 3 twelfths in my model.
“In my model there are 2 groups of 3 twelfths, with 23 of a group of 3 twelfths left over.
- Discuss Mia’s method with your partner and then with the class.
