The tricks here is to focus on the denominator of the fraction.
First make both fractions have the same denominator.
7/11 has denominator 11
4/9 has denominator 9
Then for 7/11, multiply both the numerator and denominator by the denominator of the other fraction which is 9.
This will give:
=(7 x 9)/(11 x 9)
=63/99
Then for 4/9, multiply both the numerator and denominator by the denominator of the other fraction which is 11.
This will give:
=(4 x 11)/(9 x 11)
=44/99
Comparing the two fractions, you can see that 63/66 > 44/99. Thus 7/11 is greater.
Since the temperature increased, you would 'add' the degrees together to get the correct answer.
50.7+23.9= 74.6
The high temperature was 74.6 F
I hope this helped! Merry Christmas!

Answer:
16 mls of the 75% solution and 20 mls of the 0.57% solution.
Step-by-step explanation:
Set up a system of equations:
Let x = volume of 75% solution and y be volume of 57% solution
0.75x + 0.57y = 36*0.65
0.75x + 0.57y = 23.4.......(1)
x + y = 36.........(2)
From equation (2):
y = 36 - x
Substituting this into equation(1):
0.75x + (0.57(36 - x) = 23.4
0.75x + 20.52 - 0.57x = 23.4
0.18x = 23.40 - 20.52 = 2.88
x = 2.88/0.18
x = 16
so from equation (2): y = 36-16 = 20.
12 divided by 3 equals 4. And the. Parentheses means multiply, so 4x4=16
Hope this helps! Good luck!
