What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

We have:

When Ron cycles, his maximum speed is 20 km/h when Ron runs, his maximum is 7 m/s.

= 20 km/h = 20(1000)/(60×60) m/s

= 5.55 m/s

7 > 5.55

The greater is 7 m/s.

Shop 1

3.99 tube: buy 2 get 1 free

2 tube cost = 2×3.99 = 7.98

Each unit cost = 7.98/3 = 2.66

Shop 2

3.99 a tube with 20% off:

= 20% of 3.99

= (20×3.99)/100

= 0.798

The cost of 1 tube = 3.99 - 0.798 = 3.192

He will pay the least amount of money at shop 1

Thus, the 7 m/s is greater when he is running and he will pay the least amount of money at shop 1.
