# Question #6696a

Aug 18, 2017

$757$ days in the U.S. or $909$ days in the U.K.

#### Explanation:

All we need to know is convert a gallon to millilitres. However, the value of a $\text{gallon}$ is inconsistent with the countries that use it.

A U.S. gallon is equal to 3785.41178 mL.

We take this value and divide it by , giving us how long the medicine will last.

$\frac{3785.41178}{5}$

$= 757.082356$

$\approx 757$

Thus, the medicine will last $757$ days.

A U.K. gallon is equal to 4546.09188 mL.

$\frac{4546.09188}{5}$

$= 909.218376$

$\approx 909$

Thus, the medicine will last $909$ days.

Hope this helps :)
