A tea company is making a special blend of two teas for aa customer. The ratio of Kenyan tea to Darjeeling tea in the blend is 4 to 5. How much Darjeeling tea is in 90 ounces of the blend?

50

Math 
Jessica,
Thanks! But how did you get that..?

Math 
Knights,
darjeeling tea to the ratio of the entire blend is 5 (in the ratio it is given) / 9 (sum of both teas) = 5/9
so, 5/9 * 90 ounces = 50 ounces
thus the answer is 50 ounces. sorry for being unclear 
Math 
Ms. Sue,
He might have gotten it by using a proportion.
5/9 = x/90
9x = 450
x = 50

You're fine. I also need help on a couple others.
A survey of 500 people found that 1 lout of 20 had at least one bird as a pet. How many people who were surveyed owned at least one bird? 
Math 
Jessica,
1* out of* 20

Math 
Knights,
so just like Ms. Sue said, you can you use a proportion. 1/20 would be the people owning at least one bird. So, 1/20 * 500 = 25. We get 25 people who were surveyed and owned at least one bird. Next time just post another question I guess :D

Math 
Jessica,
Was this a smart remark? "Next time just post another question I guess :D" If so, I'm not really in the mood.. but if you meant it I do have another question........

Math 
Knights,
Uh...I meant like post another entire question, not like a whole chain of them.

Math 
Ms. Sue,
I think he meant to click Post a New Question. That way everyone is alerted that it is a new question, not just a continuation of a previous question.

Math 
Knights,
I agree with Ms. Sue.

Math 
Jessica,
K. I'm sorry I didn't understand what way you were saying it. Good greef.
