Step-by-step explanation:
See Attachment for Complete Question
Given
[tex]Ratio = \frac{12}{15}[/tex]
Required
Determine its equivalent proportion
[tex]Ratio = \frac{12}{15}[/tex]
Factorize the given expression
[tex]Ratio = \frac{3 * 4}{3 * 5}[/tex]
Divide the numerator and denominator by 3
[tex]Ratio = \frac{4}{5}[/tex]
We apply the same steps to the given options as follows:
1.
[tex]Ratio = \frac{21}{28}[/tex]
Factorize
[tex]Ratio = \frac{7 * 3}{7 * 4}[/tex]
Divide the numerator and denominator by 7
[tex]Ratio = \frac{3}{4}[/tex]
This is not an equivalent proportion of [tex]\frac{12}{15}[/tex]
2.
[tex]Ratio = \frac{20}{25}[/tex]
Factorize
[tex]Ratio = \frac{5 * 4}{5 * 5}[/tex]
Divide the numerator and denominator by 5
[tex]Ratio = \frac{4}{5}[/tex]
This is equivalent to [tex]\frac{12}{15}[/tex] because they both simplify to [tex]\frac{4}{5}[/tex]
There's no need to check the last option;
Hence, the option that answers the question is [tex]\frac{20}{25}[/tex]
