Answer: 16
Work Shown:
fl oz = fluid ounce
qt = quart
32 fl oz = 1 qt
4*32 fl oz = 4*1 qt
128 fl oz = 4 qt
If she has 128 fluid ounces of water, then she can fill up the 8 fl oz water bottle a total of 128/8 = 16 times. This of course assumes that there aren't any spills.
Laura can fill her water bottle 16 times with 4 quarts of water.
What do we mean by Proportion?
Quantities are said to be in Proportion when we can relate them in a certain ratio. This ratio can be used to determine what quantity of one good is equivalent to a certain quantity of the other good. When we equate two ratios, we are using Proportion.
How do we solve the given question?
We are said that there are 32 fluid ounces in 1 quart. This can be represented in the ratio of 32:1.
Laura has 4 quarts of water. We assume that this quantity is x fluid ounces. This can be represented in the ratio of x:4.
By proportion, these ratios are equal, that is,
32:1 = x:4
or, 32/1 = x/4.
Multiplying both sides by 4, we get
(32/1)*4 = (x/4)*4
or, 128 = x
∴ Laura has 128 fluid ounces of water.
We are informed that her water bottle can hold 8 fluid ounces. To determine the number of times Laura can fill her water bottle, we simply divide the quantity by the capacity, that is,
The number of times Laura can fill her water bottle = 128/8 = 16
∴ Laura can fill her water bottle 16 times with 4 quarts of water.
