What is 12/13 + 7/8? I don't know

[From: ] [author: ] [Date: 11-06-10] [Hit: ]
You come out with 96/104 + 91/104 respectively. Then you just add 96 and 91, which turns out to be 187. Then it becomes 187/104,then simplify it.= 1.......
The answer is either:

1
2
19
21

I'm guessing you're supposed to round it, so 2.

You solve it by first finding a common denominator for both fractions. In this case it is 104.

8 x 13 = 104

So it would be 12 over 13 times 8, and 7 over 8 times 13.

You come out with 96/104 + 91/104 respectively. Then you just add 96 and 91, which turns out to be 187. Then it becomes 187/104, then simplify it.

12/13 + 7/8

= [(12 X 8) + (7 X 13)] / (13 X 8)
= [(96) + (91)] / (104)
= (187) / (104)
= 187 / 104
= 1.7981

Rounding will be 2

Thank you
