Combine 2/5k-3/5+1/10k

join

\frac{2}{5} k - \frac{3}{5} + \frac{1}{10} k

\frac{- 6 + 5 k}{10}

Solution steps

\frac{2}{5} k - \frac{3}{5} + \frac{1}{10} k

Factor out common term

k

= k (\frac{2}{5} + \frac{1}{10}) - \frac{3}{5}

\frac{2}{5} + \frac{1}{10} = \frac{1}{2}

= k \frac{1}{2} - \frac{3}{5}

Join

k \frac{1}{2} - \frac{3}{5} : \frac{- 6 + 5 k}{2 \cdot 5}

= \frac{- 6 + 5 k}{2 \cdot 5}

Multiply the numbers:

2 \cdot 5 = 10

= \frac{- 6 + 5 k}{10}
