\[\frac{2}{5} - \frac{1}{7}\]find the lowest common denominator

OpenStudy (anonymous):

Alright. I'm going to break down the process for you. Step 1: Find a Common Denominator Find the least common multiple (LCM) of 5 and 7. Obviously, it's 35 since \(7 \times 5 = 35\). Step 2: Adapt the fractions by multiply the numerator and denominator of the fraction(s) by the same number so that the LCM is in the denominator. \[\frac 25 - \frac17 \implies \frac25 \times \frac77 - \frac17 \times \frac55 \implies \frac{14}{35} - \frac{5}{35}\]Step 3: Simplify by combining like terms.\[\frac{14}{35} - \frac{5}{35} = ?\]
