yes you did

Answer 5

ok we want to get the fraction to look alike

so multiply the first fraction by 2 on top and bottom

\[5\frac{2}{5}-2\frac{9}{10}=5\frac{2}{5}*\frac{2}{2}-2\frac{9}{10}=5\frac{4}{10}-2\frac{9}{10}\]
we want to have positive outcome when we divide the fractions we borrow 1 from the 5

\[5\frac{4}{10}= 4\frac{14}{10}\]
so
we have

\[4\frac{14}{10}-2\frac{9}{10}=2\frac{5}{10}\]

Answer 6

that should say we want positive outcome when we subtract the fractions
