A:
Answer:[tex]\frac{1}{2}[/tex]Step-by-step explanation:We can see that the denominators are not the same. You cannot do that when adding or subtracting fractions.So you must LCD (Least common denominator)Multiply the denominators to get LCD:[tex]5 * 10 = 50[/tex]So our denominators are 50.Now we do crisscross multiplication:[tex]\frac{4 * 10}{50} Β - \frac{3 * 5}{50}[/tex][tex]\frac{40}{50} - \frac{15}{50}[/tex][tex]\frac{25}{50}[/tex]Simplify:[tex]\frac{25 / 2}{50 / 2}[/tex][tex]\frac{1}{2}[/tex]
