1 quart = 4 cups. So 4 x 4 will give you your answer, which is 16 cups.
Answer: 25.12
Step-by-step explanation: good luck
As the only prime factor of denominator is
2
, in fact there are three twos (
2
×
2
×
2
) we can can convert the fraction
7
8
by multiplying numerator and denominator by
5
×
5
×
5
.
Hence,
7
8
=

=

1000
=
0.875
(This is always possible if only prime factors of denominator are
2
's and
5
's - just multiply by as many
5
's and
2
's).
The rink has a dimension of 200 ft* 85 ft = 17000 
depth = 1.5 inch that becomes 
= 0.125 ft
So total volume of the water required = 17000* 0.125 = 2125 
Now 1 cubic foot of water= 7.480 gallons
Hence total gallons required are 2125 * 7.480 gallons = 15895 gallons.
I think 75 Percent is your answer Please let me know if you get this right
