<PRE><B>Question 58177</B>
How do I add these numbers together and divide by 2 to find a real number?
7/8 and 9/10
-----------
Get the same denominator on both fraction:
The least common multiple of 8 and 10 is 40
Rewrite each fraction with 40 as its denominator:
7*5/8*5  + 9*4/10*4
=35/40 + 36/40
=71/40
Now, divide by 2:
[71/40]/2
=71/[40*2]
=71/80
