To express the number of apples sold as fresh fruit in fraction form, we can represent the total number of apples as a fraction of the total picked apples.
After Sara discarded the defective apples, she was left with:
- Total apples picked: 200
- Discarded apples: 20
The number of apples sold as fresh fruit is 180.
In fraction form, this can be represented as:
\[ \text{Fraction of apples sold as fresh fruit} = \frac{\text{Number of fresh apples}}{\text{Total apples picked}} = \frac{180}{200} \]
To simplify this fraction:
\[ \frac{180}{200} = \frac{180 \div 20}{200 \div 20} = \frac{9}{10} \]
Thus, the fraction of apples sold as fresh fruit is \(\frac{9}{10}\).
