If C is inversely proportional to T, when C=1/6 and T=4/7, find C when T=10.

• Math-II -

the formula is

C= K/T

1/6=K/4/7 <-- I use Cross multiplication

K=4/42

• Math-II -

1/6=K/(4/7)
K = 1/6 * 7/4 = 7/24

C(T) = (7/24) / T
C(10) = 7/24 / 10 = 7/240

YES!! thanks to your help! @Steve ... My mistake.. I multiplied 6 and 7, the one I should multiply by 6 is 4 not 7.. gee, I always forget it.. Thank you again! :)
