Question HelpHome Heating Repair Marge's home is heated by hot water circulating in pipes. Recently, the1system developed a small leak. It loses 3, milliliters every 18 minutes. Use this complex fraction tofind the change of the amount of water in the system per minute.

Answer 1

Complex Fractions

Also known as mixed fractions, complex fractions have three parts: an integer part a numerator, and a denominator.

The fraction

`3(1)/(2)`

Can be converted to a simple fraction by adding the integer to the fraction as follows:

`3(1)/(2)=3+(1)/(2)=(6+1)/(2)=(7)/(2)`

The system has a water leak that makes it lose 7/2 milliliters of water every 18 minutes.

To find the change of the amount of water per minute, we divide:

`((7)/(2))/(18)=(7)/(2\cdot18)=(7)/(36)`

The change is -7/36 milliliters per minute
