For how many integers \(T\) is \(\dfrac{T}{40}\) between \(\dfrac{3}{55}\) and \(\dfrac{5}{7}\)?
Values T > 21 work, and then Max value is 28.
So 22 - 28 work.
That is 7 values.
3 ,4 ,5 ,6 ,7 ,8 ,9 ,10 ,11 ,12 ,13 ,14 ,15 ,16 ,17 ,18 ,19 ,20 ,21 ,22 ,23 ,24 ,25 ,26 ,27 ,28>>Total==26 such integers
3 / 40 > 3 / 55 and: 28 / 40 < 5 / 7
