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

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.$\frac{14}{35} - \frac{5}{35} = ?$
