After Mia gave [tex]\(\frac{1}{4}\)[/tex] of her milk to Dante, Dante had twice the amount of milk as Mia. What was the ratio of the amount of milk Mia had to the amount of milk Dante had initially?



Answer :

Sure! Let's solve this step-by-step.

First, let's introduce variables to represent the initial amounts of milk:
- Let [tex]\( M \)[/tex] be the amount of milk Mia had initially.
- Let [tex]\( D \)[/tex] be the amount of milk Dante had initially.

### Step 1: Express the Situation Mathematically
1. Mia gave [tex]\(\frac{1}{4}\)[/tex] of her milk to Dante.
- The amount of milk given to Dante is [tex]\(\frac{1}{4}M\)[/tex].
- After giving the milk away, Mia has [tex]\( M - \frac{1}{4}M \)[/tex] amount of milk left, which simplifies to [tex]\(\frac{3}{4}M\)[/tex].

2. Dante receives the milk from Mia.
- Dante's new amount of milk is [tex]\( D + \frac{1}{4}M \)[/tex].

### Step 2: Condition based on the Problem
Dante ends up having twice the amount of milk as Mia after receiving the milk. Mathematically, we can write this condition as:
[tex]\[ D + \frac{1}{4}M = 2 \left(\frac{3}{4}M\right) \][/tex]

### Step 3: Simplifying the Equation
Next, we simplify the equation:
[tex]\[ D + \frac{1}{4}M = 2 \cdot \frac{3}{4}M \][/tex]
[tex]\[ D + \frac{1}{4}M = \frac{6}{4}M \][/tex]
[tex]\[ D + \frac{1}{4}M = \frac{3}{2}M \][/tex]
[tex]\[ D = \frac{3}{2}M - \frac{1}{4}M \][/tex]
[tex]\[ D = \frac{6}{4}M - \frac{1}{4}M \][/tex]
[tex]\[ D = \frac{5}{4}M \][/tex]

### Step 4: Find the Ratio
We now have [tex]\( D = \frac{5}{4}M \)[/tex]. To find the ratio of the amount of milk Mia had to the amount of milk Dante had initially, we compare [tex]\( M \)[/tex] to [tex]\( \frac{5}{4}M \)[/tex].

Thus, we can express it as a ratio:
[tex]\[ M : D = M : \frac{5}{4}M \][/tex]

Dividing both parts of the ratio by [tex]\( M \)[/tex]:
[tex]\[ 1 : \frac{5}{4} \][/tex]

To get rid of the fraction, multiply both parts by 4:
[tex]\[ 4 : 5 \][/tex]

### Conclusion
The ratio of the amount of milk Mia had to the amount of milk Dante had at first is [tex]\( 4 : 5 \)[/tex].
