Question

UpStudy AI · Accepted Answer

To determine how many bottles Mrs. Chua used to store her oil, follow these steps:

**Given:**
- Total oil poured = $$ 8 $$ liters
- Oil per bottle = $$ \frac{4}{5} $$ liters

**Step 1: Understand the Problem**
We need to find out how many bottles are required to hold $$ 8 $$ liters of oil when each bottle holds $$ \frac{4}{5} $$ liters.

**Step 2: Set Up the Calculation**
The number of bottles needed can be found by dividing the total amount of oil by the amount each bottle can hold.

$$
\text{Number of bottles} = \frac{\text{Total oil}}{\text{Oil per bottle}} = \frac{8}{\frac{4}{5}}
$$

**Step 3: Perform the Division**
Dividing by a fraction is the same as multiplying by its reciprocal.

$$
\frac{8}{\frac{4}{5}} = 8 \times \frac{5}{4} = \frac{40}{4} = 10
$$

**Answer:**
Mrs. Chua used **10 bottles** to store the $$ 8 $$ liters of oil.
