Required

Select all true statements

For any option to be true, it must satisfy the following condition.

$Days * Food = 23$

Option (a):

$Days = 6$

$Food = 4\frac{1}{6}$ per day

So, we have:

$Days * Food = 6 * 4\frac{1}{6}$

$Days * Food = 6 * \frac{25}{6}$

$Days * Food = 25$

This is not true because: $25 \ne 23$

Option (b):

$Days = 10$

$Food = 2\frac{2}{23}$ per day

So, we have:

$Days * Food = 10 * 2\frac{2}{23}$

$Days * Food = 10 * \frac{48}{23}$

$Days * Food = \frac{480}{23}$

$Days * Food = 21$ --- approximated

This is not true because: $21 \ne 23$

Option (c):

$Days = 8$

$Food = 3\frac{1}{8}$ per day

So, we have:

$Days * Food = 8 * 3\frac{1}{8}$

$Days * Food = 8 * \frac{25}{8}$

$Days * Food = 25$ --- approximated

This is not true because: $25 \ne 23$

Option (d):

$Days = 11$

$Food = 2\frac{1}{11}$ per day

So, we have:

$Days * Food = 11 * 2\frac{1}{11}$

$Days * Food = 11 * \frac{23}{11}$

$Days * Food = 23$ --- approximated

This is true because: $23 = 23$

Option (e):

$Days = 7$

$Food = 3\frac{2}{7}$ per day

So, we have:

$Days * Food = 7 * 3\frac{2}{7}$

$Days * Food = 7 * \frac{23}{7}$

$Days * Food = 23$ --- approximated

This is true because: $23 = 23$
