Guest guest Posted October 17, 2003 Report Share Posted October 17, 2003 How many grams of 2.5% hydrocortisone cream should be mixed with 360g of 0.25% cream to make a 1% hydrocortisone cream? This is what I have so far: 2.5% 0.75 ------ 2.25 1% 0.25% 1.5 ----- 2.25 I'm not sure if this is right. (1.5/2.25)* X = 360g and solve for X. I need help. Thanks in advance.
