Question

What mixed number is equivalent to 18/8

Answer 1

Cupcakes answer is a correct solution but we need to know the multiple choice answers because your teacher is probably using other mixed numbers than the simplest form one just to make it harder for u

Answer 2

The mixed number to 18/8 is 2 and 1/4
To find this out you multiply 8 to get to 18, yet 8 only goes to 16 before going over 18, so 8 can multiply 2 times.
The 2 will be your whole number 
and since there is 2 numbers left (18-16=2) that would be the numbers left over giving you 2 2/8.
yet the 2/8 can be simplified to 1/4 giving you 2 1/4 as your answer.
