Question

If 160 oz of tomatoes are required for 15 servings of soup, find is the amount of tomatoes required for 1 serving.

• A. 9.6 oz
• B. $9.\overline{6}$ oz
• C. 10.6 oz
• D. $10.\overline{6}$ oz

Answer 1

The correct option is D $10.\overline{6}$ oz

Given:
Amount of tomatoes required for 15 serving of soup = 160 oz

Amount of tomatoes required for 1 serving = 160 ÷ 15

Using long division:

$$\begin{array}{c}\mathrm{10.66..}\\ 15160\\ -\underset{–}{15}2\\ 100\\ -\underset{–}{90}\\ 100\\ -\underset{–}{90}\\ 10\end{array}$$
Hence,
160 ÷ 15 = 10.66...oz (∴ Non-terminating decimal)
i.e.,
Amount of tomatoes required for 1 serving = $10.\overline{6}$ oz
