2/3 = 8/12
5 1/4 = 21/4 = 63/12
63 divide by 8 is 7.875
7 batches should be your answer
hope this helps
If u think of it this way
8*4=32 it has to be smaller than that so my best guess would be
C) 20 square units
The answer is A- 35/84
Proportional means that two things are equivalent to each other
Therefore, the ratio 10/24 has to be equal to another fraction
So when you put these fractions side by side 10/24 = 35/84 you multiply the #'s to see if this is correct
so 10 * 84 = 840 and 24 * 84 = 2016 then 35 * 24 = 840 and 84 * 24 = 2016
So the fractions now are 840/2016 = 840/2016
We can easily see that these fraction are proportional (equal)
Therefore the answer is once again 35/84
Hey!
---------------------------------------
Solution:
77.50 = 0.15x + 10
77.50 - 10 + 0.15x + 10 - 10
67.50 = 0.15x
0.15x = 67.50
0.15x/0.15 = 67.50/0.015
x = 450
---------------------------------------
Check:
77.50 = 0.15(450) + 10
77.50 = 67.50 + 10
77.50 = 77.50

Answer:
450 text messages can be sent when the monthly charge is $77.50!
