Question 6
Salil wants to put a picture in a frame. The picture is $7\frac{3}{5}$cm wide. To fit in the frame the picture cannot be more than $7\frac{3}{10}$cm wide. How much should the picture be trimmed?

Answer 1

$\text{Given: The width of the picture}=\text{7}\frac{\text{3}}{\text{5}}\text{cm and the width of picture frame}=\text{7}\frac{\text{3}}{\text{10}}\text{cm}$
$\text{Therefore, the picture should be trimmed}=7\frac{3}{5}-7\frac{3}{10}=\frac{38}{5}-\frac{73}{10}=\frac{76-73}{10}=\frac{3}{10}\text{cm}$
$\text{Thus, the picture should be trimmed by}\frac{\text{3}}{\text{10}}\text{cm}$.
