The given ratio can be expressed as a fraction by placing the part on the
left as the numerator and the part on the right as the denominator.
- The number of scooters and hoverboards altogether is 48
The given values are;
Ratio of number of scooters to number of hoverboards = 3:5
Number of scooters, s = 18
Number of scooters and hoverboards altogether = Required
Solution;
Let s, represent the number of scooters and let h, represent the number of hover boards, expressing the given ratio as a fraction gives;
[tex]\dfrac{3}{5} = \dfrac{18}{h}[/tex]
Therefore;
3 × h = 18 × 5 = 90
[tex]h = \dfrac{90}{3} = 30[/tex]
The number of hover boards, h = 30 hoverboards
Number of scooters and hoverboards altogether, A = h + s
∴ A = 30 + 18 = 48
- The number of scooters and hover boards altogether, A = 48
