To solve this problem, we can use the rule of three.

- The ratio between the mass in kilograms and in pounds is constant for every value of the mass
- Therefore, the mass in kilograms corresponding to 11 pounds can be found by writing the following equation:
Where
x is the mass in kilograms corresponding to 11 pounds.
Solving the equation for x, we find:
4-(

=4-(4)+111
=111 since 4 and -4 cancel each other out
=4-(4)+111
=111 since 4 and -4 cancel each other out
