Ineed solving 12 1/4 - 5 2/3
i’m having trouble

6 7/12

Step-by-step explanation:

We need to get a common denominator, which is 12

12 1/4 - 5 2/3

12 1/4*3/3 - 5 2/3*4/4

12 3/12 - 5 8/12

We will need to borrow from the 12 since 3/12 is less than 8/12.  Write the 1 we borrow as 12/12

11 + 12/12 + 3/12 - 5 8/12

11 15/12 - 5 8/12

6 7/12

i think ur answer is   (3,-1)

i belive those are the ones that are under 90 degreese.
