Enter the ratio as a fraction in lowest terms 2 ft to 10 in.

6 / 5

Step-by-step explanation:

1) you take the 2 feet and change it to inches by multiplying 2 by 12 because there is 12 inches in  each foot.

2) you find the greatest common factor of 12 and 10 which is 2

3) you divide both of the numbers by your GCF of 2 which is 6/5

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
