Question

-4 5/4 + 8/9 GIVING 30 POINTS PLEASE HELP THE INTERNET IS GIVING ME ALL SORTS OF DIFFERENT ANSWERS.

Answer 1

We are given the following:

`-4(5)/(4)+(8)/(9)`

The first thing we need to do is convert the mixed numbers into improper fractions.

`4(5)/(4) = (21)/(4)`

Now, we find the LCM (Least Common Multiple) of 4 and 9, which is 36. Then we adjust the fractions based on the LCM.

`=-(189)/(36) +(32)/(36)`

Next, we apply the fraction rule,
`(a)/(c)+(b)/(c) = (a+b)/(c)` to the expression based on our information.

`(-189+32)/(36)`

Then, we add the numbers
`-189+32=-157`, writing the fraction as:

`(-157)/(36)`

Apply the fraction rule,
`(-a)/(b)=-(a)/(b)`.

`-(157)/(36)`

Finally, convert the improper fractions back to mixed numbers, and hence our solution:

`-(157)/(36) = -4(13)/(36)`

Hope this helps!
