Question

(-4/7)(-7/9)
would this be-28/45???

Answer 1

7*9 is not 45, it is 63

So you should have

28/63

You then reduce this by dividing each piece by the GCF 7

28/7 = 4
63/7 = 9

So the final answer is 4/9

Answer 2

Alternatively, you can cancel the '7' terms and you can see how it will almost immediately lead you to 4/9

Answer 3

I meant to put 5 there thats why is said it was45
