Which equation is used to solve this problem ?

A veterinarian needs to examine 10 litters of kittens. He checks 2 1/2 littlers one week and 6 1/10 litters the next week. How many litters does he still need to examine ?

• $2\ \frac{1}{2\ }-\ 6\ \frac{1}{10}\ +\ 10\ =\ Remaining\ Litters$

• $2\ \frac{1}{2}\ +\ 6\ \frac{1}{10}\ +\ l\ =\ 10\ Litters$

Multiple Choice

What is the solution ?
