Question

9/16 + (-9/2)

Answer 1

-3 15/16

Answer 2

First, forget about the negative sign.  

Convert 9/2 into sixteenths, which is 144/16.  

Now, remember that adding a negative to a number is just like subtracting that number.

So, the problem is basically, 9/16 - 144/16.

Once you pass zero, your answer becomes negative.

When I get to zero, I still have 135/16 left, so my answer becomes

-135/16.

Now simplify this by dividing 135 by 16, which is 8 with a remainder.  I divided on a calculator so my remainder was a decimal.  To find it as a fraction, I can multiply 16 by 8, and subtract the product from 135:

16 x 8 = 128

135 - 128 = 7.

So the answer is  - 8 and 7/8, or negative eight and seven eighths.

It's not as complicated as it sounds.

Answer 3

-63/16

Answer 4

9/16 + (-9/2)

=(9+(-9 * 8))/16

=(9-72)/16

=-63/16

=-3.93

Answer 5

9/16 - 9/2=

9/16 - 72/16= because you need to get the denominators the same first

-63/16=

Answer 6

9/16 - 72/16 = -63/16
