Salil wants to put a picture in a frame. The picture is $${\left({7}\right)}\frac{{3}}{{5}}{c}{m}$$ wide. To fit the frame the picture cannot be more than $${\left({7}\right)}\frac{{3}}{{10}}{c}{m}$$ wide. How much should the picture be trimmed ?

Width of picture $$={7}\frac{{3}}{{5}}{c}{m}=\frac{{38}}{{5}}{c}{m}$$

Width of picture to fit the frame $$={7}\frac{{3}}{{10}}=\frac{{73}}{{10}}{c}{m}$$

So, measure of picture that should be trimmed $$=\frac{{38}}{{5}}-\frac{{73}}{{10}}=\frac{{{76}-{73}}}{{10}}=\frac{{3}}{{10}}{c}{m}$$
