Energy content of different foods are as follows:

Wheat 3.2 Joules
Rice 5.3 Joules
Potatoes (cooked) 3.7 Joules
Milk 3.0 Joules

Which food provides the least energy and which provides the maximum?
Express the least energy as a fraction of the maximum energy.

Answers (1)

In the given table, we can see that milk provides the least energy and rice provides the maximum energy.
Fraction of least energy to the maximum energy = \frac{3.0}{5.3}=\frac{3.0 \times 10}{5.3 \times 10}=\frac{30}{53}
