# what is 4/5-1/2 im so confused

$\frac{4}{5}$ - $\frac{1}{2}$ First, find the least common denominator (LCD) of the two fractions.  Factors of 5: 5, 10. Factors of 2: 2, 4, 6, 8, 10. The LCD is 10. Second, make the denominators the same as the LCD. / Your problem should look like: $\frac{4x2}{5x2}$ - $\frac{1x5}{2x5}$ Third, simplify. The denominators are now the same. / Your problem should look like: $\frac{8}{10}$ - $\frac{5}{10}$ Fourth, join the denominators. / Your problem should look like: $\frac{8-5}{10}$ Fifth, simplify. / Your problem should look like: $\frac{3}{10}$ Answer as fraction: $\frac{3}{10}$ Answer as decimal: 0.3
