A is the correct answer. When put into calculator, the decimals ends.
8:15 or 8 to 15 would be the ratio because you compare 8 quarters to 15 coins.
Pythagorean Theorem: a^2 + b^2 = c^2
a = 6
c = 9
b = ?
6^2 + b^2 = 9^2
36 + b^2 = 81
b^2 = 81 - 36
b^2 = 45
b = sqrt(45)
b = 6.71 miles
The gcf is 3 the lcm is 48 :^)
