Ok so this is what my question is asking and saying:

Question

Guess My Fraction and Win!

. if I add the fraction to 4/9, I need to find a common denominator. The smallest common denominator i could use is 18.

. if you add 4/9 to find my fraction, the sum is an improper fraction or a mixed-number.

Then has these fractions: 7/8, 2/3, 7/9, 1/2, 5/6, 3/4, 1/6, 1/3. In boxes under the question.
Do you guys have any idea what this improper or mixed-number fraction is?!?

Answer 1

4/9 = 8/18
so you need to add something bigger than 10/18
convert the choices to have a denominator of 18, and pick all those bigger than 10/18

for example, 4/9 + 5/6 = 8/18 + 15/18 = 23/18 = 1 5/18
That is not the only possibility
