Answer:

Step-by-step explanation:

we can take common factor of -1 in the denominator

and now multiply and divide by -1

To model this you will create to be equivalent fraction of models. The first model will show 3/4, and the second model will show an equivalent version of 3/4 using fractional parts the size of 1/8. See picture. There are 6/8.
Out of 6/8 you can make 2 groups of 3/8. 3/8 + 3/8 = 6/8.
You have two days worth of seef left.
