Determine the lowest common denominator for each sum or difference. see attached thank you

Answer 1

The fractions with common denominator 10 are:

`(3)/(2)-(4)/(5),5-(7)/(10)`

next, the fractions with common denominator 12 are:

`(7)/(6)+(-(5)/(12)),-(3)/(4)+(-(2)/(3))`

finally, for the common denominator 24, we have:

`(13)/(24)+(7)/(12),(1)/(8)-(5)/(3)`
