Neko [114]

Answer:

To the first question the answer would be > because you can change -3/4 to -9/12. Since these are negative numbers -5 is greater than -9.

The answer the second one would be B because I change all the fractions to decimals and 6/11 equals 0.54545454 and goes on and on So it was the greatest number (in decimal form). Also negaitve numbers are the least. :) Hope this helps

Answer:

The change of concentration surely made the difference since the last drink contained more juice with respect to the water

Step-by-step explanation:

The concentration of a drink

We can know how much of a certain ingredient there is with respect to the entire mix. This is known as the concentration and is commonly expressed in percentage %

Sylvia and her friends made a drink with 6 quarts of pineapple juice in 4 quarts of sparkling water. The total quantity of water is 10 quarts, so the concentration of pineapple juice is

\frac{4}{10}=\frac{2}{5}=40\%

The next week, their drink consisted of 5 quarts of pineapple juice and 3 quarts of sparkling water, so the new concentration is

\frac{5}{8}=62.5\%

The change of concentration surely made the difference since the last drink contained more juice with respect to the water
