प्रश्न

Salil wants to put a picture in a frame. The picture is 7 `3/5` cm wide. To fit in the frame the picture cannot be more than 7 `3/10` cm wide. How much should the picture be trimmed?

 

उत्तर

Width of picture = `7 3/5 = 38/5 cm`

Required width = `7 3/10 = 73/10 cm`

The picture should be trimmed by = `(38/5 - 73/10)`

= `((38 xx 2)/(5 xx 2) - 73/10) = (76- 73)/10 = 3/10` cm
