Steps 2

Step 1

and 3

Step 4

(1)

1/2 - 1/4 =

*This problem may be solved by either reducing the fraction 4/10 to 2/5 or by changing

the fraction 1/5 to have the common denominator of 2/10.

Answer: 4/10 - 1/5 = 2/5 - 1/5 = 1/5

Answer: 4/10 - 1/5 = 4/10 - 2/10 = 2/10 = 1/5

thereby using the least common denominator and eliminating the reduction to lowest

terms in the final answer.
