Question

Shonali want 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 the picture should she need to be trimmed?

• A. cm
• B. cm
• C. cm
• D. cm

Answer 1

The correct option is C cm

Width of the picture = $7\frac{3}{5}cm=\frac{38}{5}cm$
Width of picture frame =$7\frac{3}{10}cm=\frac{73}{10}cm$
Picture she need to be trimmed = $\frac{38}{5}cm-\frac{73}{10}cm$
= $\frac{3}{70}cm$
