5/6 – 6/12<br><br>I am lost bc I'm not a math person so pls help me?
vovangra [49]

First, we must find the common denominator (12)            ✵

10/12-6/12            ✵                 ✵                              ✵                              ✵

Now, why 10?                                     ✵                   ✵                      ✵

Because we CAN'T just take the denominator and change it; we must change both the denominator AND the numerator:

✵                                      •          -                                      ○          

4/12                  ✧                             ✩                                  ✶            ✺         ✱  

We can simplify, or reduce, this fraction:                  ✱  ✱

1/3              ✩                              ✦                                        ✤

I hope it helps!
