Question

What percentage of the given strip shaded red?
Also, find the corresponding decimal representation.

• A. 4%, 0.04
• B. 50%, 0.5
• C. 40%, 0.4
• D. 5%, 0.05

Answer 1

The correct option is B 50%, 0.5

The given strip has a total of 8 parts, out of which 4 are shaded red.

Therefore, the shaded fraction is
$=\frac{4}{8}=\frac{1}{2}$

$\Rightarrow \frac{1}{2}\text{of the strip is shaded red}=\frac{1}{2}\times 100=50\%$

$50\%\text{can be expresed as}\frac{50}{100}=0.5$

$\text{Hence 50\% portion of the strip is}\text{shaded red, which is equal to 0.5.}$
