Step-by-step solution for: Formulating Rations With the Pearson Square - 1.618 - Extension
It looks like you've uploaded a diagram related to a mixture problem, specifically involving alligation (a method used in chemistry and pharmacy to find the ratio in which two or more ingredients at different concentrations must be mixed to produce a mixture of desired concentration).
Let’s analyze the image and solve the problem step by step.
---
The diagram shows a cross (or alligation) method with four values:
- Top left: 47.0 → This is likely the concentration of one ingredient (e.g., supplement mixture).
- Bottom left: 10.0 → Concentration of the other ingredient (grain mixture).
- Right side:
- Top: 5.0 parts
- Bottom: 32.0 parts
- Center: 15% → The desired concentration of the final mixture.
We are to determine how much of each mixture (supplement and grain) should be combined to get a 15% mixture, using the alligation method.

Alligation is used to find the ratio of two ingredients with different concentrations to achieve a desired concentration.
The formula for alligation is:
$$
\text{Ratio} = \frac{\text{Higher concentration} - \text{Desired}}{\text{Desired} - \text{Lower concentration}}
$$
But in this case, the diagram already gives us the parts:
- Supplement mixture: 5.0 parts
- Grain mixture: 32.0 parts
And we can see that:
- Supplement mixture has 47.0% (likely)
- Grain mixture has 10.0%
- Desired mixture: 15%
Let’s verify if the parts make sense.
---
We use the alligation cross:
```
47.0% (Supplement)
\
\ 15%
\ /
X
/ \
/ \
10.0% (Grain)
```
Now compute the differences:
- Difference between 47.0 and 15:
$ 47.0 - 15 = 32.0 $
- Difference between 15 and 10.0:
$ 15 - 10.0 = 5.0 $
So, the ratio of supplement : grain is:
$$
\text{Supplement} : \text{Grain} = 5.0 : 32.0
$$
Wait — this seems reversed!
In alligation, the difference from higher to desired goes to the lower concentration, and vice versa.
Let’s clarify:
- Supplement: 47.0% → too high
- Grain: 10.0% → too low
- Desired: 15%
So:
- Amount of grain needed (to dilute): $ 47.0 - 15 = 32.0 $
- Amount of supplement needed: $ 15 - 10.0 = 5.0 $
So the ratio of supplement : grain is:
$$
\text{Supplement} : \text{Grain} = 5.0 : 32.0
$$
This matches what’s shown on the right side of the diagram.
> But wait — in the diagram, 5.0 parts is next to 47.0, and 32.0 parts is next to 10.0.
That means:
- 5.0 parts of supplement mixture (47.0%)
- 32.0 parts of grain mixture (10.0%)
Yes — this makes sense.
---
To make a 15% mixture:
- Mix 5.0 parts of supplement mixture (47.0%)
- With 32.0 parts of grain mixture (10.0%)
The total parts = $ 5 + 32 = 37 $ parts
So the ratio is:
$$
\boxed{5 : 32}
$$
Or as a fraction:
- Supplement: $ \frac{5}{37} $ of the total
- Grain: $ \frac{32}{37} $ of the total
---
Check the weighted average:
$$
\text{Final concentration} = \frac{(5 \times 47.0) + (32 \times 10.0)}{37} = \frac{235 + 320}{37} = \frac{555}{37} = 15.0\%
$$
✔ Confirmed!

The diagram correctly shows an alligation calculation to mix:
- 5.0 parts of 47.0% supplement mixture
- 32.0 parts of 10.0% grain mixture
to obtain a 15% mixture.
✔ Answer: The correct mixing ratio is 5 parts supplement to 32 parts grain.

✔ Alligation Method Overview:
Alligation is used to find the ratio of two ingredients with different concentrations to achieve a desired concentration.
The formula for alligation is:
$$
\text{Ratio} = \frac{\text{Higher concentration} - \text{Desired}}{\text{Desired} - \text{Lower concentration}}
$$
But in this case, the diagram already gives us the parts:
- Supplement mixture: 5.0 parts
- Grain mixture: 32.0 parts
And we can see that:
- Supplement mixture has 47.0% (likely)
- Grain mixture has 10.0%
- Desired mixture: 15%
Let’s verify if the parts make sense.

🧮 Step-by-step Verification:
We use the alligation cross:
```
47.0% (Supplement)
\
\ 15%
\ /
X
/ \
/ \
10.0% (Grain)
```
Now compute the differences:
- Difference between 47.0 and 15:
$ 47.0 - 15 = 32.0 $
- Difference between 15 and 10.0:
$ 15 - 10.0 = 5.0 $
So, the ratio of supplement : grain is:
$$
\text{Supplement} : \text{Grain} = 5.0 : 32.0
$$
Wait — this seems reversed!
In alligation, the difference from higher to desired goes to the lower concentration, and vice versa.
Let’s clarify:
- Supplement: 47.0% → too high
- Grain: 10.0% → too low
- Desired: 15%
So:
- Amount of grain needed (to dilute): $ 47.0 - 15 = 32.0 $
- Amount of supplement needed: $ 15 - 10.0 = 5.0 $
So the ratio of supplement : grain is:
$$
\text{Supplement} : \text{Grain} = 5.0 : 32.0
$$
This matches what’s shown on the right side of the diagram.
> But wait — in the diagram, 5.0 parts is next to 47.0, and 32.0 parts is next to 10.0.
That means:

Yes — this makes sense.

✔ Final Answer:
To make a 15% mixture:
- Mix 5.0 parts of supplement mixture (47.0%)
- With 32.0 parts of grain mixture (10.0%)
The total parts = $ 5 + 32 = 37 $ parts
So the ratio is:
$$
\boxed{5 : 32}
$$
Or as a fraction:
- Supplement: $ \frac{5}{37} $ of the total
- Grain: $ \frac{32}{37} $ of the total

✔ Verification:
Check the weighted average:
$$
\text{Final concentration} = \frac{(5 \times 47.0) + (32 \times 10.0)}{37} = \frac{235 + 320}{37} = \frac{555}{37} = 15.0\%
$$
✔ Confirmed!

📌 Conclusion:
The diagram correctly shows an alligation calculation to mix:
- 5.0 parts of 47.0% supplement mixture
- 32.0 parts of 10.0% grain mixture
to obtain a 15% mixture.
✔ Answer: The correct mixing ratio is 5 parts supplement to 32 parts grain.
