If the results of the following two questions are non-zero natural numbers, find the minimum value of R and S (1) r divided by 5 times 1 / 3 (2) 6 / 7 times s divided by 0.6 Want formula + answer

If the results of the following two questions are non-zero natural numbers, find the minimum value of R and S (1) r divided by 5 times 1 / 3 (2) 6 / 7 times s divided by 0.6 Want formula + answer

(1)R/5*1/3=R/15≥1
R≥15
The minimum value of R is 15
(2)6/7*S/0.6=10/7 S≥1
R≥7/10
The minimum value of S is 7 / 10
