The correct answer is Option A , D , E.
A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other.
Ratio in it's simplest form means when the ratio can't be simplified anymore by cancelling out the common factors.
The ratio in Option(A) can't be simplified anymore because 29 is a prime number.
The ratio in Option(B) can be simplified to 1 / 7.
The ratio in Option(C) can be simplified to 5 / 2.
The ratio in Option(D) can't be simplified.
The ratio in Option(E) can't be simplified because 19 is prime number.
Hence, the correct answer is Option A , D , E.

Step-by-step explanation: Hope this helps
The volume for the 0.26% is 250 ml and the volume for the 0.06% is 750 ml.
Step-by-step explanation:
In the solution the techinician wants to create there's a total of:
salt = 1*0.11/100 = 0.0011
So the sum of the salt from the other two solutions must be equal to that, since the quantity of salt in each is given by:
salt1 = volume1*0.06/100 = volume1*0.0006
salt2 = volume2*0.26/100 = volume2*0.0026
The sum of the from the two solutions must be equal to the final one:
salt = salt1 + salt2
0.0011 = 0.0006*volume1 + 0.0026*volume2
while the volume of the solutions must be equal to 1 liter:
volume1 + volume2 = 1
If we isolate volume1 on the second equation and replace that on the first one we have:
volume1 = 1 - volume2
0.0006*(1 - volume2) + 0.0026*volume2 = 0.0011
0.0006 - 0.0006*volume2 + 0.0026*volume2 = 0.0011
0.002*volume2 = 0.0011-0.0006
0.002*volume2 = 0.0005
volume2 = 0.0005/0.002 = 0.25 liters = 250 ml
volume1 = 1 - 0.25 = 0.75 liters = 750 ml
or 0.6
