Option B model shows the percent of beads that are blue.
Solution:
Fraction of beads blue = [tex]\frac{4}{20}[/tex]
To convert it into percent multiply the fraction by 100.
[tex]$\text {Percent of} \ \frac{4}{20}=\frac{4}{20}\times 100\%[/tex]
[tex]$=\frac{4\times 100}{20} \%[/tex]
Cancel the common factors, we get
= 20%
[tex]$=\frac{20}{100}[/tex]
This means total number of boxes 100 and shaded in blue color 20.
Therefore option 2 represents [tex]\frac{20}{100}[/tex].
Hence option B model shows the percent of beads that are blue.
