Answer: 2/35

Step-by-step explanation: First you have to find the minimun common multiplier (MCM). 5 and 7 are prime numbers (only divisible by one and themselves), so they MCM is the product of both, resulting in 5 times 7 equals 35. Now you find the equavilent equation to 1/7 and 1/5 to make them in 5/35 and 7/35, respectively. Finally the clear difference is 2/35. (7/35 - 5/35)
