Question

Convert each mixed number to an improper fraction and solve by subtracting use the LCD

Answer 1

To solve is:


`1 (1)/(4) - 1 (1)/(5)`

making it into an improper fraction:


`(1+4)/(4) - (1+5)/(5)`



`(5)/(4) - (6)/(5)`

bringing to a common denominator (which is 20, since they have no factors in common)


`(5*5)/(20) - (6*4)/(20)`



`(25)/(20) - (24)/(20)`

the answer is then:

`(1)/(20)`
