How do i solve this problem, show me in detail as i am missing something i am missing. i have tried the problem any way i can think of and never end up with the correct answer.
10 x (actually a dot, but i do not have a dot on my computer key board) 7/2 - (43/8 - - 16/5)?
you

1057/40

Step-by-step explanation:

10*7/2 - (43/8- - 16/5)=x

Let's do the parentheses first.

To do this you have to make both numbers have a common denominator (the bottom number).

43/8=215/40 and -16/5=-128/40

Then you subtract -128/40 from 215/40

215/40- -128/40=343/40

Now you have 10*7/2 - 343/40

If you multiply 10 by 7/2 you get 70/2, which simplifies to 35.

You now have 35-343/40

Once again we must make both numbers have a common denominator.

35/1=1400/40

(1400/40)-(343/40)= 1057/40
