Answer:
Mixture A is a stronger mixture.
Step-by-step explanation:
We are given the following in the question:
Mixture A:
3 parts concentrate to 5 Parts water
Mixture B:
4 parts concentrate to 7 Parts Water.
We have to find the stronger mixture.
We calculate the ration of concentrate to the water and the mixture with a greater ration is more stronger.
Ratios:
[tex]M_A = \dfrac{3}{5}\\\\M_B = \dfrac{4}{7}[/tex]
Comparison:
[tex]\dfrac{21}{35} > \dfrac{20}{35}\\\\\dfrac{3}{5}>\dfrac{4}{7}\\\\M_A > M_B[/tex]
Thus, Mixture A is a stronger mixture.
