3/25+4/27+2/25+40/50+23/27
= (3/25+2/25+40/50)+(4/27+23/27)
=1+1
=2
3/25 + 4/27 + 2/25 + 40/50 + 23/27
= (3/25 + 2/25 + 20/25) + ( 4/27 + 23/27)
= 1 + 1
= 2
\(\frac{3}{25}+\frac{4}{27}+\frac{2}{25}+\frac{40}{50}+\frac{23}{27}\)
\(=\left(\frac{3}{25}+\frac{2}{25}+\frac{40}{50}\right)+\left(\frac{4}{27}+\frac{23}{27}\right)\)
\(=\left(\frac{6}{50}+\frac{4}{50}+\frac{40}{50}\right)+\left(\frac{4}{27}+\frac{23}{27}\right)\)
\(=1+1\)
\(=2\)
\(\frac{3}{25}+\frac{4}{27}+\frac{2}{25}+\frac{40}{50}+\frac{23}{27}\)
\(\Leftrightarrow\left(\frac{3}{25}+\frac{2}{25}\right)+\left(\frac{4}{27}+\frac{23}{27}\right)+\frac{40}{50}\)
\(\Leftrightarrow\frac{1}{5}+1+\frac{40}{50}=\frac{10}{5}=2\)
=(3/25+2/25+40/50)+ (4/27+23/27)
=1+1=2

\(\frac{3}{25}+\frac{4}{27}+\frac{2}{25}+\frac{40}{50}+\frac{23}{27}\)
\(=\left(\frac{3}{25}+\frac{2}{25}\right)+\left(\frac{4}{27}+\frac{23}{27}\right)+\frac{40}{50}\)
\(=\frac{5}{25}+\frac{27}{27}+\frac{4}{5}\)
\(=\frac{1}{5}+1+\frac{4}{5}\)
\(=1+1=2\)
