Answer: 5 coins
Step-by-step explanation:
Frank found 9 coins on the floor of his car, and 3 of them were quarters. This means that 3 out of the 9 coins, or [tex]\frac{3}{9}[/tex], were quarters.
Simplifying this fraction, we get [tex]\frac{1}{3}[/tex] of the coins found in the car were quarters.
If Frank finds 15 more coins on the ground at the same ratio, then [tex]\bold{\frac{1}{3}}[/tex] of these coins will also be quarters. To find out how many quarters he will most likely find, we need to find [tex]\bold{\frac{1}{3}}[/tex] of 15:
[tex]\large \frac{1}{3} \times 15 = 5[/tex]
Therefore, Frank will most likely find 5 more quarters on the ground, assuming he finds coins at the same ratio as he did in his car.
