If 2/3 of a given number is 40, what is 2/5 of the given number?
SO if (2/5)n=200
so
n=200
(2/5)n=200/5= 40 or is it 17?

Candi, do not put a new question as an answer to somebody else's.
It may not be looked at , since we might think the first question has been answered.
'2/3 of a given number is 40'
--- (2/3)x = 40
x = 40(3/2) = 60
now 2/5 of that is (2/5)(60) = 24
Where did the 200 come from ???

not sure but thank you explain it better so I can understand where the 60 comes fro?
(2/3) x = 40
multiply both sides by 3
2 x = 120
divide both sides by 2
x = 60
multiply both sides by 3
2 x = 120
divide both sides by 2
x = 60
