Fiona says that 7% of the model is shaded.

Question

A bar diagram with 7 shaded squares and 3 unshaded squares.

Do you agree? Why or why not?
Yes, because 7 parts are shaded.
Yes, because 7 of 10 parts are shaded.
No, because StartFraction 7 Over 10 EndFraction parts shaded equals 70%.
No, because 6 parts are shaded.

Answer 1

To evaluate Fiona's statement, we first need to analyze the bar diagram with 7 shaded squares and 3 unshaded squares.

The total number of squares (shaded + unshaded) is 7 + 3 = 10 squares.

To find the percentage of the model that is shaded, we calculate:

\[ \frac{\text{shaded squares}}{\text{total squares}} = \frac{7}{10} \]

To convert this fraction to a percentage, we multiply by 100:

\[ \frac{7}{10} \times 100 = 70% \]

Therefore, Fiona's claim that 7% of the model is shaded is incorrect.

The correct conclusion would be:

No, because \(\frac{7}{10}\) parts shaded equals 70%.
