Question

a picture is 7 3/5 cm wide. how much it be trimmed to fit in a frame 7 3/10 cm wide?

Answer 1

7 3/5=73/10=7.3
7 3/5=38/5=7.6
7.7-7.3=0.4
its should be trimmed 0.4 or 2/5cm

Answer 2

Answer:

0.3 cm

Step-by-step explanation:

Since, the initial width of the frame = $7\frac{3}{5}\text{ cm}$

Let the picture is trimmed by the x cm,

Thus, the new width of the picture = initial width - x

$=7\frac{3}{5}-x$

According to the question,

$7\frac{3}{5}-x=7\frac{3}{10}$

$\implies x = 7\frac{3}{5}-7\frac{3}{10}=\frac{38}{5}-\frac{73}{10}=\frac{76-73}{10}=\frac{3}{10}=0.3$

Hence, the picture is trimmed 0.3 cm.
