To determine when the display on the scale is correct to the tenths place for $\frac{5}{6}$ ounces of basil, you need to convert the fraction $\frac{5}{6}$ into a decimal.

Conversion:

$\frac{5}{6} = 0.8333\ldots$ This is a repeating decimal, but you want the scale to display it rounded to the tenths place.

Rounding:

When rounding 0.8333 to the tenths place:

• The tenths digit is 8.
• The hundredths digit is 3, which is less than 5, so you leave the tenths place as it is.

Thus, the correct weight in decimal to the tenths place is 0.8 ounces.

Conclusion:

Hayley should stop when the scale reads 0.8 ounces.
