Help please... Every weekend, Marvin bikes to the park to play disc golf with his friends. Before leaving home, he fills his water bottle to the top. This weekend, Marvin drinks 1/2
of a liter on the way to the park. Now there is only
1/4
of a liter remaining in Marvin's water bottle.
Use an equation to find the amount of water that Marvin's water bottle holds.
To write a fraction, use a slash ( / ) to separate the numerator and denominator.
