Question

Energy content of different foods are as follows:

Food Energy content per kg

$$\begin{gathered} Wheat3.2joules \\ Rice5.3joules \\ Potatoes3.7joules \\ Milk3.0joules \end{gathered}$$

Which food provides the least energy and which provides the maximum?

Answer 1

Comparison of decimals:

Given, that the energy contents are in like decimal numbers.

$3.2,5.3,3.7,3.0$

Arrange the decimals in ascending order:

Here we compare the whole number parts first.

Therefore$3<5$

Since, $3.2,3.7,and3.0$ have the same whole number part. So, we compare the tenths digits.

$\Rightarrow 0<2<7$

We get, $3.0<3.2<3.7<5.3$ is in ascending order

Therefore, milk provides the least energy that is $3.0$ joules and rice provides the maximum that is $5.3$ joules.
