Question

What is 6 1/2 + 5 7/8= ?

Answer 1

`6 (1)/(2)` +
`5(7)/(8)`

First, add the whole numbers before doing anything else (the 5 and the 6) . / Your problem should look like: 11 +
`(1)/(2)` +
`(7)/(8)`
Second, find the least common denominator (LCD)
Multiples of 2: 2, 4, 6, 8
Multiples of 8: 8
The LCD is 8.
Third, make the denominators the same as the LCD (8) / Your problem should look like: 11 +
`(1x4)/(2x4)` +
`(7)/(8)`
Fourth, now that the denominators are the same, you can simplify. / Your problem should look like: 11 +
`(4)/(8)` +
`(7)/(8)`
Fifth, combine/join the denominators. / Your problem should look like: 11 +
`(4+7)/(8)`
Sixth, simplify. / Your problem should look like: 11 +
`(11)/(8)`
Seventh, convert
`(11)/(8)` to a mixed fraction. / Your problem should look like: 11 +
`1(3)/(8)`
Eighth, simplify. / Your problem should look like:
`12 (3)/(8)`

Answer as fraction:
`12 (3)/(8)`
Answer as decimal: 12.375
