You made lemonade and iced tea for a school fair. You made 15 gallons of lemonade and 60% is gone. About 52% of the iced tea is gone. The ratio of gallons of lemonade to gallons of iced tea was 3 : 2. a. How many gallons of lemonade are left?
b. How many gallons of iced tea did you make?
c. About how many gallons of iced tea are left?

Answers

There are few things to answer for this problem. First how many gallon of lemonade are left? You had 15 gallons and it's 60% gone. That means that 40% is left. You have to figure out how much 40% of 15 is. You do that by multiplying 15 x 0.40. The answer is 6.

Next, how much ice tea did you make? You figure this out with the ration 3:4 which can also be written as the fraction 3/4. The lemonade is the three and you know you made 15 gallons of that. 15 is 3 x 5. If you multiply the 4 times 5 also you will find out how much iced tea you made - 20 gallons.

How many gallons of iced tea are left? You figure this out by multiplying the percent left - 48% (100 - 52) by 20 gallons. 20 x 0.48 = 9.6 gallons.

What is the middle number when the numbers {5.1, –3.6, 0, –2, –1.1} are ordered from least to greatest?

Answers

|-10 - 3|

Subtract.

|-13|

Simplify:

13

The 'bigger' the negative numbers look, the smaller they are.

Therefore, Option D is correct.

5.1, -3.6, 0, -2, -1.1

Arrange from least to greatest:

-3.6, -2, -1.1, 0, 5.1

So the middle number is -1.1.
