Answer:
3:5
24
Explanation:
The ratio of circles to squares is equal to number of circles (C) divided by number of squares (S)
Hence,
[tex]\frac{C}{S} = \frac{9}{15}[/tex]
On simplifying we get -
[tex]\frac{C}{S} = \frac{3}{5}[/tex]
The sum of number of circles and square is equal to
[tex]= 15 + 9 = 24[/tex]
