Answer 2

I can help you with math problems. Here are the detailed solutions:

- $$\frac{9}{25}-\frac{7}{20}=\frac{9\times 4-7\times 5}{25\times 4}=\frac{36-35}{100}=\frac{1}{100}$$ - $$\frac{37}{42}-\frac{17}{24}=\frac{37\times 24-17\times 42}{42\times 24}=\frac{888-714}{1008}=\frac{174}{1008}=\frac{29}{168}$$ - $$\frac{11}{24}-\frac{3}{16}=\frac{11\times 4-3\times 6}{24\times 4}=\frac{44-18}{96}=\frac{26}{96}=\frac{13}{48}$$ - $$\frac{9}{16}+\frac{7}{24}-\frac{3}{8}=\frac{9\times 3+7\times 2-3\times 6}{16\times 3}=\frac{27+14-18}{48}=\frac{23}{48}$$ - $$\frac{1}{3}-\frac{1}{6}+\frac{1}{4}=\frac{1\times 4-1\times 2+1\times 3}{3\times 4}=\frac{4-2+3}{12}=\frac{5}{12}$$ - $$\frac{2}{5}+\frac{4}{15}-\frac{5}{9}=\frac{2\times 9+4\times 3-5\times 5}{5\times 9}=\frac{18+12-25}{45}=\frac{5}{45}=\frac{1}{9}$$

I hope this helps. Do you have any other math questions?
