Answer:
The ratio of boys to girls is
[tex]\frac{4}{5}:\frac{3}{5}[/tex]
Step-by-step explanation:
In a class the total number of boys and girls are 25
Total of boys are 20 and total of girls are 15
Let x be the number of boys and y be the number of girls
Given x=20 and its ratio is
[tex]x=\frac{20}{25}[/tex]
[tex]x=\frac{4}{5}[/tex]
and y=15 and its ratio is
[tex]y=\frac{15}{25}[/tex]
[tex]y=\frac{3}{5}[/tex]
Therefore the ratio of boys to girls is
[tex]x:y[/tex]
[tex]\frac{4}{5}:\frac{3}{5}[/tex] or
[tex]4:3[/tex]
