combine like terms to create an equivalent expression.\n$\frac{9}{8}m+\frac{9}{10}-2m - \frac{3}{5}$

Explanation:

Step1: Combine m - terms

$\frac{9}{8}m-2m=\frac{9}{8}m-\frac{16}{8}m=\frac{9 - 16}{8}m=-\frac{7}{8}m$

Step2: Combine constant - terms

$\frac{9}{10}-\frac{3}{5}=\frac{9}{10}-\frac{6}{10}=\frac{9 - 6}{10}=\frac{3}{10}$

Step3: Write the equivalent expression

The equivalent expression is $-\frac{7}{8}m+\frac{3}{10}$

Answer:

$-\frac{7}{8}m+\frac{3}{10}$
