Answer:
cross multiply
Explanation:
-First you multiply ps times 100 which gives you 100ps and then 100 x 1 which is 100.
-then u make them equal to each other so you get 100ps=100.
-resulting in ps= 1 and I think either you plug the value of ps back in the equation or you solve it beyond that which then you will the multiply ps which gives you 1,46ps=100 then u divide 100/1,46 giving you the value of ps. I think so
